The driver is required for some third party engineering software we have to run, but I can rig a spare machine to run some of these other jobs without it for a bit. I'll report back if/when I have a new panic. I will note though that the driver comes from the debian provided packages (albeit from backports instead of stable).I realise that, but it's not part of Debian proper and none of us signed up to debug drivers that don't come with source.
Fair enough.I've attached a new set of kernel messages captured from some runs without the nvidia driver loaded, but with the rest of the setup the same. It doesn't quite seem to be tickling the same code path - this time it's an invalid opcode message instead of a NULL pointer dereference. I'll let it go for a while more to see if I can get the same style message to back. Unfortunately I don't exactly know how to reproduce it.
Thanks, Brian
