I am not a VM hacker -- can you tell me where to start? what do you suspect it is?
If the user stops seeing the error with preemption disabled, is your theory nulled, or does that just mean the problem is agitated by preemption?
I don't think Arjan was using ReiserFS, so its from grow_buffers...
I appreciate your help.
