Hi Daniel, I've installed your libva patch:
libva: libva version 0.32.0 libva: va_getDriverName() returns 0 libva: Trying to open /usr/local/lib/dri/i965_drv_video.so libva: va_openDriver() returns 0 vainfo: VA API version: 0.32 vainfo: Driver version: Intel i965 driver - 1.0.15.pre1 No Changes. With iommu switched off there are less frequent hangs but there still are :-(. dmesg shows: WARNING: at drivers/gpu/drm/i915/i915_drv.c:354 gen6_gt_force_wake_get+0x1f/0x3c [i915]() Hardware name: 4236NGG Modules linked in: snd_hda_codec_conexant fbcon font bitblit softcursor i915 thinkpad_acpi nvram drm_kms_helper drm fb fbdev cfbcopyarea video iwlagn backlight cfbimgblt cfbfillrect e1000e snd_hda_intel snd_hda_codec intel_agp intel_gtt agpgart Pid: 0, comm: swapper Not tainted 3.1.0-rc4+ #1 Call Trace: <IRQ> [<ffffffff8102fcf2>] ? warn_slowpath_common+0x78/0x8c [<ffffffffa0113fd9>] ? i915_vblank_swap+0x6/0x6 [i915] [<ffffffffa010c484>] ? gen6_gt_force_wake_get+0x1f/0x3c [i915] [<ffffffffa01140e2>] ? i915_hangcheck_elapsed+0x109/0x29a [i915] [<ffffffffa0113fd9>] ? i915_vblank_swap+0x6/0x6 [i915] [<ffffffff81039799>] ? run_timer_softirq+0x195/0x222 [<ffffffff8103466f>] ? __do_softirq+0x7f/0x106 [<ffffffff813b4f2c>] ? call_softirq+0x1c/0x30 [<ffffffff81003396>] ? do_softirq+0x31/0x67 [<ffffffff810348a0>] ? irq_exit+0x44/0xa5 [<ffffffff81015cdd>] ? smp_apic_timer_interrupt+0x85/0x95 [<ffffffff813b468b>] ? apic_timer_interrupt+0x6b/0x70 <EOI> [<ffffffff811d5022>] ? intel_idle+0xcd/0xe9 [<ffffffff811d4ffe>] ? intel_idle+0xa9/0xe9 [<ffffffff812ae307>] ? cpuidle_idle_call+0xa0/0xdb [<ffffffff81000840>] ? cpu_idle+0x52/0x75 [<ffffffff81677b60>] ? start_kernel+0x401/0x40c In this special case the gpu was successfully reset and continued normally. Any other ideas?
