Comment 1 Bevis King 2004-09-07 10:43:05 UTC
I am seeing this same fault with the -520 kernel on FC3test1. 
Enclosed below is my messages log relating to it.

Comment 2 Bevis King 2004-09-07 10:46:10 UTC
Created attachment 103536 [details]
/var/log/messages as a user with NFS-mounted home logs in

This shows the Oops as a user with an NFS mounted home logs in.  Server is an
RH7.3 box operating as NFSv3/UDP.

Comment 3 Bevis King 2004-09-07 13:27:53 UTC
This seems to be an upstream bug, and the linux- subrelease is
basically a two line patch that fixes it.  Any chance of a suitable
RPM set for Fedora Core 3 test 1?   Regards, Bevis.

Comment 4 H.J. Lu 2004-10-11 17:04:42 UTC
2.6.8-1.603 is OK.
