GPU hang crashing kernel error dump head
Hello simon, is there a possibility to provide more data from your system as instructed in https://01.org/linuxgraphics/documentation/how-report-bugs? Wondering if you have SNB = Lenovo Thinkpad T420 Laptop with i5-2520M or something else. Hi yes its the standard t420 with i5-2520m sandy bridge cpu. I'll try building the drm-tip branch.. Hi Simon, once your provide results from drm-tip and logs please change the status of the bug to Reopen... Hmm there seemes to be something wrong with the build guide (https://01.org/linuxgraphics/documentation/build-guide-0) there is no drm-tip branch within "git://anongit.freedesktop.org/git/drm-intel" Ok i build the kernel from the drm-intel-nightly branch and the problems seem not to occur anymore on my first tests yet. ^^ Thanks, drm-tip here: https://cgit.freedesktop.org/drm-tip/ Ok the Problem now occured with the nightly kernel too, sadly i couldnt get a log file because the laptop didnt react any more and i had to do an acpi-emergency-poweroff (pressing the power button 6s). Is there a way to save the error log somehow automatically if that happens again? Ahh seems like i'ld have to use the netconsole kernel module, to log the problem, think i'll try that when i have more time, at least with the never kernel the bug i much more rare. ^^ Hello Simon, Once you have time again, could you please try to get the drm-tip with the following command: "git clone https://anongit.freedesktop.org/git/drm-tip.git" This way it won't be need any special configuration to download the kernel. Also this other command: "export GIT_SSL_NO_VERIFY=1" , please. Finally once your provide more information, please change "NEEDINFO" to "REOPEN", thank you. Hello Elizabethx, well the problem only occurred once since I build the kernel from the drm-intel-nightly branch, so it seems to be some kind of rare race condition and therefore hard to track.. Wouldn't it make sense to downgrade to an older kernel where the bug occurred more often, to be able to get some full debug log? (In reply to Simon from comment #11) > Hello Elizabethx, > well the problem only occurred once since I build the kernel from the > drm-intel-nightly branch, so it seems to be some kind of rare race condition > and therefore hard to track..

In this case this isn't the best option because it would be necessary to reproduce the bug in the last kernel too. If you can't reproduce it again it'll be assumed that the bug was on the previous kernel and in the new one is fixed. Please let me know if you find the way to reproduced it with the new kernel. Thank you. I finally got some backtrace: [43297.051536] pipe A vblank wait timed out [43297.051581] ------------[ cut here ]------------ [43297.051647] WARNING: CPU: 2 PID: 2590 at drivers/gpu/drm/i915/intel_display.c:12823 intel_atomic_commit_tail+0xf9e/0xfc0 [i915] [43297.051649] Modules linked in: x86_pkg_temp_thermal kvm_intel snd_hda_codec_hdmi iwldvm kvm mac80211 irqbypass pcspkr iwlwifi thinkpad_acpi snd_hda_codec_conexant i915 snd_hda_codec_generic iosf_mbi i2c_algo_bit drm_kms_helper lpc_ich syscopyarea mfd_core sysfillrect sysimgblt fb_sys_fops drm snd_hda_intel snd_hda_codec snd_hwdep mei_me intel_gtt snd_hda_core agpgart mei [43297.051684] CPU: 2 PID: 2590 Comm: X Not tainted 4.12.0-rc4-01465-gd90972f #1 [43297.051686] Hardware name: LENOVO 4180CE9/4180CE9, BIOS 83ET76WW (1.46 ) 07/05/2013 [43297.051688] task: ffff8fdad38fc240 task.stack: ffffb4a681204000 [43297.051731] RIP: 0010:intel_atomic_commit_tail+0xf9e/0xfc0 [i915] [43297.051733] RSP: 0018:ffffb4a681207900 EFLAGS: 00010286 [43297.051736] RAX: 000000000000001c RBX: 0000000000000000 RCX: 000000000000001f [43297.051738] RDX: 0000000000000001 RSI: 0000000000000002 RDI: ffffffff8fc475d0 [43297.051740] RBP: ffffb4a6812079a8 R08: 0000000000000000 R09: 000000000000001c [43297.051741] R10: ffffb4a681207900 R11: 74756f2064656d69 R12: ffff8fdad0430000 [43297.051742] R13: 0000000000000000 R14: 0000000000000000 R15: 0000000000000001 [43297.051745] FS: 00007f62f912d8c0(0000) GS:ffff8fdade280000(0000) knlGS:0000000000000000 [43297.051747] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [43297.051749] CR2: 0000000001b84b50 CR3: 000000020ac96000 CR4: 00000000000406e0 [43297.051751] Call Trace: [43297.051764] ?

By comment #6 it seems that the hang problems were fixed with drm-tip, and the later traces you got may be related to bug 102617.

GPU hang started when trying to open second X Server.
Ok I added an other dmesg because it happened again, this time with 4.14.5 when I tried to open a second X-Server. Judging by the '[209087.576496] [drm:drm_atomic_helper_commit_cleanup_done [drm_kms_helper]] *ERROR* [CRTC:36:pipe A] flip_done timed out' messages, seems to be same issue that bug 103712, there is already a fix, but haven't made it upstream yet, so let's wait for it. Would hard disabling the vblank fix it? Because however I seem to have tearing anyway, so disabling it shouldn't really hurt I think.. I uncommented the if in intel_atomic_wait_for_vblanks, for the function to always return instead of waiting, that seems to fix my problem with no negative side effect:
static void intel_atomic_wait_for_vblanks(struct drm_device *dev,
struct drm_i915_private *dev_priv,
unsigned crtc_mask)
{
unsigned last_vblank_count[I915_MAX_PIPES];
enum pipe pipe;
int ret;
//if (!crtc_mask)
return;
//...
}
Still GPU hangs in 4.15.3, without my proposed patch stated above..

I commented out "//drm_atomic_helper_wait_for_flip_done(dev, state);" now in intel_atomic_commit_tail(..) in drm/i915/intel_display.c, that seems to fix some problems probably, at least I did a 2,5h test playing Xonotic and didn't get any GPU crashes on Xonotic with that patch yet. I still "get i915 0000:00:02.0: Resetting chip after gpu hang" though with introduction level of OpenTomb ( https://github.com/opentomb/OpenTomb/ ) with an additional console message: "i965: Failed to submit batchbuffer: Input/output error" That's probably some bug in OpenTomb, but anyway a program bug shouldn't hang the GPU right? Also on an Ivy Bridge that hang doesn't happen. First of all. Sorry about spam. This is mass update for our bugs. Sorry if you feel this annoying but with this trying to understand if bug still valid or not. If bug investigation still in progress, please ignore this and I apologize! If you think this is not anymore valid, please comment to the bug that can be closed. If you haven't tested with our latest pre-upstream tree(drm-tip), can you do that also to see if issue is valid there still and if you cannot see issue there, please comment to the bug. Maarten, any comments from you? Reporter, do you still have the issue? Simon, do you still have this issue? If so, Can you send dmesg from boot with kernel parameters drm.debug=0x1e log_buf_len=4M. Just tested with 4.18.9 kernel and it's sadly still broken: [ 5820.211896] [drm:drm_atomic_helper_wait_for_flip_done [drm_kms_helper]] *ERROR* [CRTC:39:pipe A] flip_done timed out [ 5830.238577] [drm:drm_atomic_helper_wait_for_dependencies [drm_kms_helper]] *ERROR* [CRTC:39:pipe A] flip_done timed out [ 5840.265261] [drm:drm_atomic_helper_wait_for_dependencies [drm_kms_helper]] *ERROR* [CONNECTOR:52:LVDS-1] flip_done timed out [ 5850.291892] [drm:drm_atomic_helper_wait_for_dependencies [drm_kms_helper]] *ERROR* [PLANE:28:primary A] flip_done timed out [ 5860.318557] [drm:drm_atomic_helper_wait_for_flip_done [drm_kms_helper]] *ERROR* [CRTC:39:pipe A] flip_done timed out ...
