It's not impossible that the nvidia driver messed with interrupts in 
a way causing your problem.

There have been too many problems in the kernel in the past that 
turned out to be caused by binary-only modules after developers
had wasted much time on them.

A kernel module has the full power to break _everything_ and we cannot 
debug their blob.

Please try without this driver ever loaded since booting
(you should even be able to reproduce this problem without running X).

If you still see it, please send the output of:
- dmesg -s 1000000
- cat /proc/interrupts
