First try compiling xf86-video-mach64 from git. The second most recent
commit sounds relevant to your problem.

If you're looking for workarounds, you can always try disabling EXA in
your xorg.conf. It is probably okay just to disable the Composite /
RENDER part with Option "ExaNoComposite" "true".

The best way is to go through the git history. You should find a series
of commits by George Sapountzis adding EXA support to mach64. I added it
a year and a half ago to r128 and was only able to do so by reading
these commits and a bunch in the radeon driver.

The log file should probably go in a pastebin next time.
