Wow, that's a nasty problem.  Looks like bumblebee is tickling some sort
of serious hardware bug in the NVIDIA card and its interaction with the
system PCI bus in a way that's causing random memory corruption (at least)
and possibly messing with other things, like bus traffic to the drives.

I'm not sure the software is really at fault there, since that sort of
corruption should not be possible at the hardware level, but that also
means that the problem is likely to persist for quite a while since
hardware can't be as easily patched.

This is probably going to require the bumblebee upstream figure out what
it's doing that's tickling this hardware bug and hopefully work around it.
