I needed the unused PCI VGA card for testing another machine,

Putting it back in results in normal behavior (no panic).
Sounds like something is messing with free'd memory through a stale pointer
and happens to be trashing that spin mutex as a result. Not sure on how to
track it down however.
The funny thing is that it happens in exactly this same place,
and only when I pull the VGA card out. ;)
5.3-<mumble> didn't do that to me for my DS10 when I took the VGA card
SRM setting CONSOLE=serial right? (should be but heh...)
