Today I got a lot i915 warnings on a thinkpad t400, here is the something copied from syslog:
[Known issue?]

The gpu refuses to clear the write fifo. Which means it pretty much disappeared into nirvana. The kernel _should_ detect this condition and try to reset the gpu. Furthermore it should dump a useful information into i915_error_state in debugfs. Can you please attach that (rebooting obviously destroy the contents of that file)?

Also, your version of your kernel, xf86-video-intel, mesa and libdrm are relevant.

Yours, Daniel

Today I got a lot i915 warnings on a thinkpad t400, here is the something copied from syslog:
[Known issue?]

The gpu refuses to clear the write fifo. Which means it pretty much disappeared into nirvana. The kernel _should_ detect this condition and try to reset the gpu. Furthermore it should dump a useful information into i915_error_state in debugfs. Can you please attach that (rebooting obviously destroy the contents of that file)?

Sorry, I did not save the debugfs content.

I can not always reproduce this issue, I will send that to you when I see the call trace next time.

Also, your version of your kernel, xf86-video-intel, mesa and libdrm are relevant.

kernel: 3.4.0
xf86-video-intel: xorg-x11-drv-intel-2.16.0-1.el6.x86_64
mesa: mesa-dri-drivers-7.11-1.el6.x86_64
libdrm: libdrm-2.4.25-1.el6.x86_64

Today I got a lot i915 warnings on a thinkpad t400, here is the something copied from syslog:
[Known issue?]

The gpu refuses to clear the write fifo. Which means it pretty much disappeared into nirvana. The kernel _should_ detect this condition and try to reset the gpu. Furthermore it should dump a useful information into i915_error_state in debugfs. Can you please attach that (rebooting obviously destroy the contents of that file)?

Quoted 4 lines

Sorry, I did not save the debugfs content.

I can not always reproduce this issue, I will send that to you when I see the call trace next time.

Np.

Also, your version of your kernel, xf86-video-intel, mesa and libdrm are relevant.

kernel: 3.4.0
xf86-video-intel: xorg-x11-drv-intel-2.16.0-1.el6.x86_64
mesa: mesa-dri-drivers-7.11-1.el6.x86_64
libdrm: libdrm-2.4.25-1.el6.x86_64

Hm, both the ddx driver and mesa are comparetively old and we've fixed and aweful lot of bugs since these got released. Can you try upgrading to the latest released versions of each?

Thanks, Daniel
