--- Comment #18 from Jakob Nixdorf flocke@shadowice.org --- Ok, just finished bisecting, this is the first commit with the dmesg errors:
e110c98cae0ceae47db6cf26c08707505ce92479 is the first bad commit commit e110c98cae0ceae47db6cf26c08707505ce92479 Author: Alex Deucher alexander.deucher@amd.com Date: Sun Jan 27 22:13:52 2013 -0500
r600g: don't emit WAIT_UNTIL on cayman/TN (v2)
It shouldn't be needed and older kernels don't support it.
v2: Replace with PS partial flush as before.

And if I remember correctly I first noticed it with kernel 3.7.5 or 3.7.6, but I thing this was also around the time this mesa commit was pushed so it may have nothing to do with this kernel versions.
