Beginning with kernel version 2.6.38 (and not 2.6.37.5), continuing to 3.1.8, at boot I get:
kernel: render error detected, EIR: 0x00000010 kernel: IPEIR: 0x00000000 kernel: IPEHR: 0x00000000 kernel: INSTDONE: 0xfffffffe kernel: INSTPS: 0x00000000 kernel: INSTDONE1: 0xffffffff kernel: ACTHD: 0x00000000 kernel: page table error kernel: PGTBL_ER: 0x00000001 kernel: [drm:i915_report_and_clear_eir] *ERROR* EIR stuck: 0x00000010, masking
It happened with no previous kernels (and still doesn't). As near as I can tell this causes no problem. I'd like to know what it means. I've diffed all the files in drivers/gpu/drm/i915 between versions 2.6.37.5 and 2.6.38. If no one knows what this is about I would appreciate information about how to narrow down what causes it. For instance, is it unlikely to be in the gem stuff? The gem stuff is a large portion of the difference.
