<pre>Some relevant bits from the log. Pretty sure that the MMIO writes to b010/b020
aren't an issue... although I am a bit surprised you're seeing them. I wonder
if firefox is somehow managing to invoke PMPEG. Or it could be the fifo getting
fed random stuff causing it.
Also, your kernel is compiled with gcc-4.8. Are you using a libdrm before
2.4.48 also compiled with gcc-4.8? If so, upgrade, or use an older gcc.

MEM_FAULT? A little coincidental that the get pointer is at a page boundary.
But this is pre-nv50, so there's no paging... what does MEM_FAULT mean?
