Created attachment 44752 [details] output of lspci After resume I see the following error in my dmesg: PM: early resume of devices complete after 2.512 msecs i915 0000:00:02.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16 i915 0000:00:02.0: setting latency timer to 64 render error detected, EIR: 0x00000010 page table error PGTBL_ER: 0x00000001 [drm:i915_report_and_clear_eir] *ERROR* EIR stuck: 0x00000010, masking render error detected, EIR: 0x00000010 page table error PGTBL_ER: 0x00000001 There is another bug #15187 concerning render error after resume, but my PFTBL_ER is different so I decided to file a separate report. Fortunately, in my case this error does not lead to system hang. I have not encountered this error with 2.6.35 and xf86-video-intel-2.12.0. Now I am using 2.6.37 and xf86-video-intel 2.14.0. I have attached output of lspci.
Can you check if the 2.6.36.y kernels are affected too, please?
I have checked 2.6.36 and 2.6.36.3. Unfortunately, both these kernels exhibit this behaviour. I've also tried to downgrade xf86-video-intel to 2.13.0, but the bug persisted.
The reported error is a "host memory access through an invalid PTE". Which is very bizarre because all the PTEs point to a real page (the unused entries point to the same scratch page). We do that because the GPU doesn't respect page boundaries when prefetching.... But this a violation during CPU access!
In 2.6.38.1 the bug has changed: now I get the following: render error detected, EIR: 0x00000010 page table error PGTBL_ER: 0x00000003 [drm:i915_report_and_clear_eir] *ERROR* EIR stuck: 0x00000010, masking render error detected, EIR: 0x00000010 page table error PGTBL_ER: 0x00000003

Please retest on 3.3.
Probably fixed by now. Please re-open if not.
