[OOPS] - Linux 2.6.8, NFSv3
From: Chris Rankin
Date: Sat Aug 14 2004 - 09:17:25 EST
Hi,
I see that there's a thread about this already, but
those oopsen don't look quite like mine. This oops was
generated on a UP 1 GHz PIII machine, kernel compiled
with gcc 3.4.1.
The NFS mount was over UDP to another machine running
2.6.8, which hasn't oopsed yet.
Cheers,
Chris
