Subject: regression(?) 3.4 -> 3.5-rc1: drm/i915 render error

Hi everyone,

Since upgrading to 3.5-rc1 (I believe) I find the following warnings
in my dmesg:
[  116.591654] [drm] capturing error event; look for more information in /debug/dri/0/i915_error_state
[  116.592888] i915: render error detected, EIR: 0x00000010
[  116.592890] i915:   IPEIR: 0x00000000
[  116.592891] i915:   IPEHR: 0x05000000
[  116.592893] i915:   INSTDONE: 0xfffffffe
[  116.592894] i915:   INSTPS: 0x0001e000
[  116.592895] i915:   INSTDONE1: 0xffffffff

[  116.592902] [drm:i915_report_and_clear_eir] *ERROR* EIR stuck: 0x00000010, masking

I attach the compresed /debug/dri/0/i915_error_state output.

Anything else I can provide?

Best wishes

Norbert
