Bug#683499: Segmentation fault in gen7_update_renderbuffer_surface()
Hi, I have an Intel HD 4000 from the i7-3770 processor. I'm still having this segfault for any GL programs (e.g. glxgears). I'm on Debian testing, libgl1-mesa-dri 8.0.5-3 I think the stack trace is pretty much the same. Program received signal SIGSEGV, Segmentation fault. gen7_update_renderbuffer_surface (brw=0x77fd8040, rb=0x61a0c0, unit=0) at gen7_wm_surface_state.c:200 200 gen7_wm_surface_state.c: No such file or directory.

Sad :( Probably worth mentioning in the upstream report though, and trying a newer kernel (3.4 or 3.5). Or is it because debugfs was not mounted at the time the hang happened?
