Sending bug reports to lkml for things that break when you have Nvidia
drivers (regardless of whether the driver has anything to do with the
problem) is generally a very good way to receive all kinds of insults.
The only thing I can suggest (other than getting rid of the nvidia
driver) is to send the bug report to the nvidia driver list.
