Hi, with today's -next I got this:
[drm] capturing error event; look for more information in
/sys/kernel/debug/dri/0/i915_error_state
i915: render error detected, EIR: 0x00000010
i915: page table error
i915: PGTBL_ER: 0x00000002
[drm:i915_report_and_clear_eir] *ERROR* EIR stuck: 0x00000010, masking
i915: render error detected, EIR: 0x00000010
i915: page table error
i915: PGTBL_ER: 0x00000002

These feel like they are becoming more common, though we have had
reports of this style of error since the dawn of time. The error means
that the CPU accessed an invalid PTE - so the most likely a missing mb
or chipset flush.
