[Intel-gfx] 915GM: render error detected, EIR: 0x00000010

[Paul Menzel]

Dear graphics folks,


using `linux-image-3.0.0-1-686-pae` from Debian Sid/unstable I noticed
the following message in `dmesg`.

        [   76.292185] [drm] capturing error event; look for more information in /debug/dri/0/i915_error_state
        [   76.294236] render error detected, EIR: 0x00000010
        [   76.294246] page table error
        [   76.294251]   PGTBL_ER: 0x00000010
        [   76.294264] [drm:i915_report_and_clear_eir] *ERROR* EIR stuck: 0x00000010, masking
        [   76.294298] render error detected, EIR: 0x00000010
        [   76.294304] page table error
        [   76.294309]   PGTBL_ER: 0x00000010

I just booted, GDM was started, I started the window manager and opened
a terminal.

I mounted the debug filesystem as documented in [1] (after the message
had appeared in `dmesg`) and just copied the
`/debug/dri/0/i915_error_state` to the attached file.

The device is an ASUS EeePC 701 4G [2].

Searching for that error message on the Web gives several hits
suggesting this error has been there for a long time [3] but is supposed
to be fixed since 2.6.33 and also 2.6.32 stable. I will try to find out
if I can find it in the system logs with earlier Linux kernels.

Other information I found on the Web with the same error message are [4–
7] where some of them suggest that this is an error which got fixed
again and again.


Thanks,

Paul
