Created attachment 52250 [details] Output of lspci -vv As per discussion on intel-gfx list, repeated hibernate/thaw cycles cause kernel errors, which eventually crash the machine. The threads: http://lists.freedesktop.org/archives/intel-gfx/2011-September/012276.html http://lists.freedesktop.org/archives/intel-gfx/2011-October/012402.html http://lists.freedesktop.org/archives/intel-gfx/2011-October/012548.html The only thing that is known for sure is that when nomodeset is passed into the kernel (tested with 3.1.0-rc9), the problem does not occur. One suggestion was to try the patch from bug #40241, i.e. https://bugs.freedesktop.org/attachment.cgi?id=50648. This did not help. Another suggestion was to add memmap=2M#512M memmap=2M#1024M to the kernel command line. It did not help. A typical kernel dump happened after 20 or so hibernate/thaw cycles. One example of what happens is below: ----------------------- [ 175.770300] BUG: unable to handle kernel NULL pointer dereference at 0000000000000010 [ 175.774934] IP: [<ffffffff81243038>] prio_tree_replace+0x4b/0x66 [ 175.779296] PGD 1f88d0067 PUD 1f88af067 PMD 0 [ 175.783593] Oops: 0002 [#1] SMP [ 175.788025] CPU 2 [ 175.788055] Modules linked in: fuse ppdev parport_pc lp parport sunrpc bnep bluetooth cpufreq_ondemand acpi_cpufreq freq_table mperf arc4 iwlagn snd_hda_codec_hdmi mac80211 snd_hda_codec_conexant uvcvideo snd_hda_intel snd_hda_codec videodev snd_hwdep media snd_seq qcserial v4l2_compat_ioctl32 usb_wwan snd_seq_device snd_pcm cfg80211 thinkpad_acpi snd_timer e1000e intel_ips iTCO_wdt iTCO_vendor_support joydev mxm_wmi snd_page_alloc snd i2c_i801 wmi rfkill pcspkr microcode soundcore ipv6 firewire_ohci sdhci_pci sdhci mmc_core firewire_core crc_itu_t i915 drm_kms_helper drm i2c_algo_bit i2c_core video [last unloaded: scsi_wait_scan] [ 175.810238] [ 175.814616] Pid: 3763, comm: gcm-apply Not tainted 3.1.0-rc9+ #105 LENOVO 4313CTO/4313CTO [ 175.819031] RIP: 0010:[<ffffffff81243038>] [<ffffffff81243038>] prio_tree_replace+0x4b/0x66 [ 175.823327] RSP: 0018:ffff8801f8bbfce8 EFLAGS: 00010207 [ 175.827099] RAX: ffff880229b84100 RBX: ffff8801f8bfb100 RCX: 0000000000000000 [ 175.829260] RDX: ffff880229b84050 RSI: ffff880229b84100 RDI: ffff88022c12b318 [ 175.831374] RBP: ffff8801f8bbfce8 R08: ffff880229b84100 R09: 0000000000000000 [ 175.833440] R10: ffff8801f8bfbd48 R11: ffff8801f8bfbd10 R12: ffff880229b84050 [ 175.835388] R13: ffff88022c12b318 R14: 0000000000000080 R15: 0000000000000000 [ 175.837373] FS: 0000000000000000(0000) GS:ffff88023bd00000(0000) knlGS:0000000000000000 [ 175.839407] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 175.841446] CR2: 0000000000000010 CR3: 00000002085a1000 CR4: 00000000000006e0 [ 175.843471] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 175.845556] DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 [ 175.847616] Process gcm-apply (pid: 3763, threadinfo ffff8801f8bbe000, task ffff8801a864ae40) [ 175.849738] Stack: [ 175.851809] ffff8801f8bbfd48 ffffffff8124327a ffff880229b84100 000000000000003d [ 175.853961] 000000000000003f 0000000000000000 000000000000003d ffff8801f8bfb0b0 [ 175.856109] ffff8801f8bfb100 ffff8801f8bfbd50 ffff88022c12b2f8 ffff8801f8bfbd48 [ 175.858296] Call Trace: [ 175.860435] [<ffffffff8124327a>] prio_tree_insert+0x16b/0x216 [ 175.862599] [<ffffffff810f12bf>] vma_prio_tree_insert+0x26/0x3c [ 175.864759] [<ffffffff810fdc3f>] __vma_link_file+0x64/0x66 [ 175.866899] [<ffffffff810fe32e>] vma_link+0x75/0x95 [ 175.869014] [<ffffffff810ffd9a>] mmap_region+0x30a/0x46b [ 175.871114] [<ffffffff81100194>] do_mmap_pgoff+0x299/0x2f3 [ 175.873205] [<ffffffff81100303>] sys_mmap_pgoff+0x115/0x164 [ 175.875334] [<ffffffff810126d0>] sys_mmap+0x22/0x24 [ 175.877409] [<ffffffff8149dd42>] system_call_fastpath+0x16/0x1b [ 175.879523] Code: 0f 0b 48 89 17 eb 16 48 89 4a 10 48 8b 4e 10 48 39 31 75 05 48 89 11 eb 04 48 89 51 08 48 8b 08 48 39 c1 74 0a 48 89 0a 48 8b 08 [ 175.879735] 89 51 10 48 8b 48 08 48 39 c1 74 0c 48 89 4a 08 48 8b 48 08 [ 175.884169] RIP [<ffffffff81243038>] prio_tree_replace+0x4b/0x66 [ 175.886469] RSP <ffff8801f8bbfce8> [ 175.888702] CR2: 0000000000000010 [ 176.196577] ---[ end trace 75df9d9a11de8acd ]--- [ 178.928408] PM: Marking nosave pages: 000000000009e000 - 0000000000100000 [ 178.928418] PM: Marking nosave pages: 00000000bb27c000 - 00000000bb282000 [ 178.928422] PM: Marking nosave pages: 00000000bb35f000 - 00000000bb40f000 [ 178.928430] PM: Marking nosave pages: 00000000bb46f000 - 00000000bb70f000 [ 178.928446] PM: Marking nosave pages: 00000000bb717000 - 00000000bb71f000 [ 178.928451] PM: Marking nosave pages: 00000000bb76c000 - 00000000bb7ff000 [ 178.928457] PM: Marking nosave pages: 00000000bb800000 - 0000000100000000 [ 178.930551] PM: Marking nosave pages: 00000001fc000000 - 0000000200000000 [ 178.930855] PM: Basic memory bitmaps created [ 178.930859] PM: Syncing filesystems ... done.

I tested hibernation/thaw cycles on one of my old machines, an HP Pavilion ZE4201 notebook, which has integrated Radeon graphics (IGP 340M, which is RS200 chip). This box is a 32-bit machine, as opposed to my ThinkPad T510, which is running 64-bit stuff. Similar behaviour on hibernate/thaw - with nomodeset, no trouble. With KMS, trouble after a few hibernate/thaw cycles (NULL pointers and other kernel dumps onto the console). Interesting. Maybe the problem is not Intel specific after all. Also, removing intel_ips module does not help.
Looks like bug #40241, which is also caused by KMS.
(In reply to comment #3) > Looks like bug #40241, which is also caused by KMS. Yeah, it is. You can see my posts there too (unfortunately). I opened a separate bug, because I was asked to do so on the intel-gfx list. As you can see from comment #2, I am suspecting now that this is not Intel specific, but rather something common to KMS code, because I got very similar symptoms on a machine that uses radeon driver (also integrated graphics, BTW). Of course, I have no proof of this, just a feeling.
If it is coming through KMS, it could probably be not intel-specific indeed. I think Jesse is working on a patch to disable KMS before suspending, this way we'll be able to rule out this possibility. Thanks for those reports, I hope we'll be able to fix it soon!
(In reply to comment #5) > If it is coming through KMS, it could probably be not intel-specific indeed. Obviously, I do not understand this code enough to tell - I'm just guessing. So, use salt in abundance. :-) All I know is that on two of my machines, with different graphics hardware, hibernation works properly when I pass nomodeset to the kernel. If I leave that option out, I get trouble after several hibernate/thaw cycles. > I think Jesse is working on a patch to disable KMS before suspending, this way > we'll be able to rule out this possibility. > > Thanks for those reports, I hope we'll be able to fix it soon! Cool. I'm ready to test anything you may have!
In an effort to confirm that this really is a regression, I remembered an old bug, that was fixed during Fedora 13: https://bugzilla.redhat.com/show_bug.cgi?id=537494 You will see from https://bugzilla.redhat.com/show_bug.cgi?id=537494#c67 there that another person confirmed that the problem was indeed fixed with a particular kernel release. So, I downloaded kernel-2.6.34.9-69.fc13.x86_64.rpm from Fedora 13 updates, installed it (into Fedora 15 - yeah, I know crazy) and did over 50 hibernate/thaw cycles on my ThinkPad T510. I am writing these comments from that session. No kernel errors, no segfaults - works fine. So, it does look like a regression, or at least looks like things have gotten worse (much worse) with newer kernels.
Just to follow up on this a bit, I cloned Linus' tree as of today (i.e. currently staged stuff for 3.2) then pulled Keith's tree (git://people.freedesktop.org/~keithp/linux drm-intel-next) over the top and compiled. Did 26 hibernate/thaw cycles and then went to check the machine. Unfortunately, I then got: --------------------------- [ 729.195407] BUG: unable to handle kernel NULL pointer dereference at 0000000000000008 [ 729.199345] IP: [<ffffffff8125121d>] __list_add+0x14/0x7f [ 729.203288] PGD 0 [ 729.207051] Oops: 0000 [#1] SMP [ 729.210874] CPU 0 [ 729.210901] Modules linked in: fuse ppdev parport_pc lp parport bnep bluetooth sunrpc cpufreq_ondemand acpi_cpufreq freq_table mperf snd_hda_codec_hdmi snd_hda_codec_conexant snd_hda_intel snd_hda_codec snd_hwdep snd_seq snd_seq_device snd_pcm thinkpad_acpi snd_timer e1000e uvcvideo rfkill snd videodev media v4l2_compat_ioctl32 qcserial usb_wwan mxm_wmi wmi snd_page_alloc microcode i2c_i801 iTCO_wdt iTCO_vendor_support pcspkr intel_ips soundcore joydev ipv6 firewire_ohci firewire_core crc_itu_t sdhci_pci sdhci mmc_core i915 drm_kms_helper drm i2c_algo_bit i2c_core video [last unloaded: scsi_wait_scan] [ 729.231392] [ 729.235351] Pid: 897, comm: dbus-daemon Tainted: G W 3.1.0+ #2 LENOVO 4313CTO/4313CTO [ 729.239316] RIP: 0010:[<ffffffff8125121d>] [<ffffffff8125121d>] __list_add+0x14/0x7f [ 729.243143] RSP: 0018:ffff88022ce57d60 EFLAGS: 00010286 [ 729.246941] RAX: ffff8801ab1454d0 RBX: 0000000000000000 RCX: 0000000000000054 [ 729.250770] RDX: 0000000000000000 RSI: ffff880229777100 RDI: ffff8801ab145520 [ 729.254604] RBP: ffff88022ce57d80 R08: ffff88020c7f28e8 R09: 00007f0aaeda4000 [ 729.258294] R10: 0000000000015ff8 R11: 0000000000015fa8 R12: ffff880229777100 [ 729.261820] R13: ffff8801ab145520 R14: ffff8802297770b0 R15: ffff8801ab1450b0 [ 729.265401] FS: 00007f0aaed80800(0000) GS:ffff88023bc00000(0000) knlGS:0000000000000000 [ 729.269032] CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b [ 729.272674] CR2: 0000000000000008 CR3: 000000022d275000 CR4: 00000000000006f0 [ 729.276338] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 729.279988] DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 [ 729.283616] Process dbus-daemon (pid: 897, threadinfo ffff88022ce56000, task ffff88022ca55c80) [ 729.287278] Stack: [ 729.290885] ffff88020c7f28e8 ffff88022c192d80 ffff88022a0bd500 ffff8801ab1454d0 [ 729.294593] ffff88022ce57d90 ffffffff810f1fe5 ffff88022ce57e10 ffffffff81055b6b [ 729.298289] 0000000000000000 ffff8801ab1450e8 ffff8801ab1450f0 ffff8801ab1450c8 [ 729.301966] Call Trace: [ 729.305664] [<ffffffff810f1fe5>] vma_prio_tree_add+0x81/0x95 [ 729.309405] [<ffffffff81055b6b>] dup_mm+0x2f3/0x488 [ 729.313143] [<ffffffff810566db>] copy_process+0x9b1/0x119c [ 729.316888] [<ffffffff811fdca6>] ? security_file_alloc+0x16/0x18 [ 729.320631] [<ffffffff81129db5>] ? get_empty_filp+0xa4/0x133 [ 729.324351] [<ffffffff81056ff0>] do_fork+0xef/0x22d [ 729.328029] [<ffffffff813daf9e>] ? sock_alloc_file+0xb3/0x114 [ 729.331672] [<ffffffff810440eb>] ? should_resched+0xe/0x2d [ 729.335300] [<ffffffff8149a9bd>] ? _cond_resched+0xe/0x22 [ 729.338914] [<ffffffff813d9388>] ? might_fault+0xe/0x10 [ 729.342532] [<ffffffff81016336>] sys_clone+0x28/0x2a [ 729.346128] [<ffffffff814a2ae3>] stub_clone+0x13/0x20 [ 729.349661] [<ffffffff814a27c2>] ? system_call_fastpath+0x16/0x1b [ 729.353249] Code: ad de 48 b9 00 02 20 00 00 00 ad de 48 89 13 48 89 4b 08 5e 5b 5d c3 55 48 89 e5 41 55 49 89 fd 41 54 49 89 f4 53 48 89 d3 41 50 <4c> 8b 42 08 49 39 f0 74 20 49 89 d1 48 89 f1 48 c7 c2 98 15 7e [ 729.361220] RIP [<ffffffff8125121d>] __list_add+0x14/0x7f [ 729.365218] RSP <ffff88022ce57d60> [ 729.369206] CR2: 0000000000000008 [ 729.439968] ---[ end trace a0f13f2533f6746a ]--- --------------------------- Followed by machine becoming weird and throwing a whole lot more kernel errors, which I could not capture any more.
