I didn't notice anyone saying they had a crash without X running. I may
have missed it.

At least it doesn't appear to be SMP related then.

Well so far neither my A7V tbird 700 nor my A7N8X-E-DX XP 1700+ have had
any crashes, and both run nvidia binary driver. Doesn't prove there
isn't a bug, doesn't prove mine won't crash, just that it seems to only
affect certain systems.

Certainly sounds kernel and certain hardware related.

The majority of the kernel is the same between those versions.

It appears on some machines.

Memtest fails to find most subtle errors, which is hardly surprising.

Well that is certainly annoying. Usually at least a nice crash dump is
nice. Freezes are not. I wonder if a kernel with deadlock debuging
enabled would be useful. alt+sysrq+stuff did nothing?

Sounds like a tricky one.
