i915: drm:i915_wait_irq EBUSY

[Niel Lambrechts]

Hi

I recently changed AccelMethod to XAA in my xorg.conf, and after
resuming (from hibernate), my X-server crashed with the following dmesg.
It was non-fatal, as I could restart X (from a black console screen -
not sure if that is related). Never had any problems suspending to
either disk/memory without this option up to now...
 
dmesg output:
ata2.00: ACPI cmd e3/00:1f:00:00:00:a0

The problem occurred on my Thinkpad W500, running OpenSUSE 11.1 with
vanilla 2.6.28.6-pae kernel, using the integrated Intel Mobile GM45
Express chipset.

Any ideas?

The chip is hung.  Don't use XAA -- it hasn't been the default or even
supported while your chipset has existed.

Sure, I needed to do that temporarily to address a startup crash in
opera, didn't know it was no longer supported though so I thought I'd
report it.
