[Bug 66673] NULL pointer dereference on BONAIRE (hd7790) after starting X server

https://bugs.freedesktop.org/show_bug.cgi?id=66673

--- Comment #5 from Dmitry Derevyanko nrndda@gmail.com --- With kernel: 3.11.3 gentoo version mesa: git(Oct 3) builded with gles xf86-video-ati: git(Oct 3) libdrm: git(Oct 3) llvm: git(Oct 3) glamor: git(Oct 3) builded without gles

I can boot to kde (with radeon.dpm=1 in kernel cmdline) but some activity in firefox leads to GPU lockup, what has nothing to do with this bug. Without gles in mesa I can't boot at all. As described before. Maybe it'll help find problem.
