Does it hang when you do anything in particular?
FWIW, this line in dmesg is probably related:
[ 141.232226] radeon 0000:01:00.0: bo ffff8804236d3400 va 0x0000001000
conflict with (bo ffff88042a018800 0x0000001000 0x0000001563)
but I'm not sure what would cause that.
<span class="quote">> I've tested TearFree when this feature was introduced in git version of

Can you try isolating the xf86-video-ati commit introducing the hang with git
bisect?</pre>
