[Nouveau] [Bug 67315] System lockup with X consuming all CPU

[bugzilla-daemon at freedesktop.org]

--- Comment #20 from Emil Velikov <emil.l.velikov at gmail.com> ---
Rick there is no need to try the BUG_ON(!data).patch

I was assuming that the data printed by nouveau indicates the CPU
pointer(rather than one from the gpu's vm), silly me.

That said, the only thing that I can think of is that either the VM is not
setup properly or data is getting overwritten somewhere :\

Either case a mmiotrace of the blob may be great to have [1], although not too
sure when I'll have some time to look into it

Cheers
Emil
