Subject: 2.6.19 nfsd oops

After running fine for 8 days, my NFS fileserver suddenly oops'd in the 
NFS (see first attachment).

Data points:
* system: Intel x86-64, Fedora Core 5
* kernel: unpatched 2.6.19 release kernel
* from the syslog, it appears that the event coincided with a Fedora 
Core 5 nfs-utils package upgrade
* the oops appears to be workqueue-related, but that might just be the 
callsite
* I recently started (again) switching clients from NFSv3 to NFSv4. 
This may or may not be related to the oops.

I've attached the dmesg and .config from 2.6.19-gbff19b1d, which is the 
kernel it is currently running.  This is just to give a better picture 
of the machine.  As I noted above, the oops was from kernel 2.6.19 not 
2.6.19-gbff19b1d.
