kernel log - system's hung

after this commit:
http://cgit.freedesktop.org/mesa/mesa/commit/?id=8ee7370c9bed0be40c5d134f0b92eb3782c6b7e9
GPU's lost stability. I've tested it on unigine-valley/xonotic(ultimate)/some
wine apps. 
Nothing segfaults,no logs, sometimes (with heavy load) gpu crashes with
standard dmesg info:
radeon 0000:01:00.0: GPU lockup CP stall for more than 10000msec etc.

kernel 3.13rc2 (dpm on by default) x86&x86_64
llvm 3.5 (svn-197173)
libdrm 2.4.50
GPU cape verde xt

is there any switch to turn off htile by now?
