Hello,

I've just found this error in my logs. It occured once so far, but I never
got it before with 3.5.0, so I'm reporting it.

[drm] capturing error event; look for more information
in /debug/dri/0/i915_error_state 
i915: render error detected, EIR: 0x00000010 
i915:   IPEIR: 0x00000000
i915:   IPEHR: 0x01000000
i915:   INSTDONE: 0xfffffffe
i915:   INSTPS: 0x0001e000
i915:   INSTDONE1: 0xffffffff
i915:   ACTHD: 0xad01f678
i915: page table error
i915:   PGTBL_ER: 0x00000001
[drm:i915_report_and_clear_eir] *ERROR* EIR stuck: 0x00000010, masking

Best,

On a quick look this is a hange in the gen4 mesa code, nothing gone wrong
that could be blamed on the kernel part of the driver. Please upgrade to
the latest mesa (maybe even try git). If you can still reproduce this (and
you've figured out a way to reliably reproduce this), please file a bug
on bugs.freedesktop.org agains mesa -> intel/i965.

Thanks, Daniel
