--- Comment #63 from Alexandre Demers 2012-07-10 00:21:56 PDT ---
Now running latest drm-next just in case. Always the same error, but with a
little something new: with regular kernel, once the GPU crashed, it stays this
way. With the drm-next branch, it loops. Attaching some files in a moment.
I just started Gnome Shell, then opened a terminal window and launched piglit
r600 tests.
I'm pretty sure (dmesg):

corresponds to (.xsession-error):
