[Nouveau] Traceback related to nouveau, possibly

[Soham Chakraborty]

Hi fellas,

I come to you to clarify/corroborate one suspicion of mine, involving
nouveau. Few days since, my laptop started to create lots of kerneloops and
the traceback always involves nouveau. I didn't intend to create a bug
report without confirming that whether or not it really is a nouveau
problem.

Here is the backtrace in all its glory, attached.

Kernel - 3.14.6-200.fc20.x86_64
Three modules are tainted and therefore it refuses to be reported to
bugzilla. They are vboxnetadp,vboxnetflt,vboxdrv.

This is the relevant part that makes me wonder about whether this involves
the driver or rather, hardware. If it is hardware, then which part should I
focus?
