I get regular and repeatable panics when using smbfs for a long time. In
that workload, I'm usually playing video from a Windows XP network
share, and after a few hours (approx. 2 - 4 hours, very irregular, but
always happens)
of constant usage (there are no other significant processes on the system), the
machine panics. It's a Celeron M laptop with 256MB RAM, and otherwise very
stable.
