Created attachment 48933 [details] [review] Use the BLT for fbdev Right, I'm still able to reproduce this on -next, but similarly only over ssh. The one time I got a hang, but had not the good sense to write it down, it looked like a buffer overrun. With the attached patch, mplayer works again, but the bug is more likely the stride mishandling that is fixed within that patch. And by accident I triggered it: [ 1399.719063] BUG: unable to handle kernel paging request at ffffc90011909540 [ 1399.719075] IP: [<ffffffff8127f687>] bitfill_aligned+0xd9/0x102 [ 1399.719093] PGD 13d80f067 PUD 13d830067 PMD 131f96067 PTE 0 [ 1399.719104] Oops: 0002 [#1] SMP [ 1399.719112] CPU 0 [ 1399.719116] Modules linked in: nfs lockd fscache auth_rpcgss nfs_acl 8021q garp stp llc sunrpc cpufreq_ondemand acpi_cpufreq freq_table mperf snd_hda_codec_hdmi snd_hda_codec_idt arc4 iwlagn mac80211 cfg80211 snd_hda_intel snd_hda_codec snd_hwdep e1000e snd_seq snd_seq_device snd_pcm snd_timer snd uvcvideo hp_wmi sparse_keymap rfkill iTCO_wdt soundcore snd_page_alloc videodev ppdev parport_pc parport wmi iTCO_vendor_support serio_raw pcspkr tpm_infineon microcode v4l2_compat_ioctl32 joydev uinput ipv6 sdhci_pci firewire_ohci sdhci mmc_core firewire_core crc_itu_t i915 drm_kms_helper drm i2c_algo_bit i2c_core video [last unloaded: scsi_wait_scan] [ 1399.719213] [ 1399.719221] Pid: 7653, comm: mplayer Not tainted 3.1.0-rc6+ #38 Hewlett-Packard HP ProBook 6360b/1620 [ 1399.719233] RIP: 0010:[<ffffffff8127f687>] [<ffffffff8127f687>] bitfill_aligned+0xd9/0x102 [ 1399.719247] RSP: 0018:ffff8801346e37e8 EFLAGS: 00010206 [ 1399.719253] RAX: 0000000000000003 RBX: 00000000000000c0 RCX: 0000000000000003 [ 1399.719260] RDX: ffffc90011909540 RSI: ffffc90011909540 RDI: ff000000ff000000 [ 1399.719267] RBP: ffff8801346e37f8 R08: ffffc90011909548 R09: 0000000000000040 [ 1399.719274] R10: 0000000000000000 R11: ffffffffffffffff R12: 0000000000000000 [ 1399.719280] R13: ffff880130a23000 R14: 00000000000000c0 R15: ffffc90011909540 [ 1399.719289] FS: 00007f7f6864b780(0000) GS:ffff88013dc00000(0000) knlGS:0000000000000000 [ 1399.719297] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 1399.719303] CR2: ffffc90011909540 CR3: 000000011a9af000 CR4: 00000000000406f0 [ 1399.719310] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 1399.719317] DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 [ 1399.719325] Process mplayer (pid: 7653, threadinfo ffff8801346e2000, task ffff8801331bc560) [ 1399.719330] Stack: [ 1399.719334] ff000000ff000000 0000000000000000 ffff8801346e3878 ffffffff8127f4c6 [ 1399.719346] 0000000100000000 ffff88013329ec00 ffff88013329ecb8 0000ffff0000ffff [ 1399.719357] ffffffff8127f5ae 0000ffff00000010 0000000600000006 0000000000000300 [ 1399.719367] Call Trace: [ 1399.719379] [<ffffffff8127f4c6>] cfb_fillrect+0x1f2/0x2da [ 1399.719388] [<ffffffff8127f5ae>] ?

Created attachment 59090 [details] [review] Validate requested panning size Applied to airlied/drm-fixes: commit 62fb376e214d3c1bfdf6fbb77dac162f6da04d7e Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Mon Mar 26 21:15:53 2012 +0100 drm: Validate requested virtual size against allocated fb size mplayer -vo fbdev tries to create a screen that is twice as tall as the allocated framebuffer for "doublebuffering". By default, and all in-tree users, only sufficient memory is allocated and mapped to satisfy the smallest framebuffer and the virtual size is no larger than the actual. For these users, we should therefore reject any userspace request to create a screen that requires a buffer larger than the framebuffer originally allocated.
