Comment # 21 on bug 98386 from baybay

Nevermind, i spoke a bit too fast...
I had nouveau.runpm=0 set and that indeed fixed this MMIO write FAULT issue.
Also, i had it set before (on older kernels) and it used to do nothing.
But that's now working.

Without nouveau.runpm=0, i still get this issue.

The lockups i had were not related to that issue and it was due to the fact
that i enabled NvBoost.
When NvBoost is enabled, i get the lockups. (either it set to 1 or 2 will
freeze the Xorg)
