Bug#516376: kernel BUG at include/linux/module.h:386! - nfsd
Package: linux-image-2.6.26-2-xen-amd64
Version: 2.6.26-17
Experienced the below yesterday on a Lenny server running as Xen Dom0,
with DomU systems mounting exported nfs filesystems (although nothing
suggests this problem is in any way Xen related). Seems very similar to
#516376 which is why I'm reporting it here (clearly whatever was fixed
in http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=518431 is not a fix
for this).

The system has only recently been installed so I can't say whether this
is a commonly occuring problem, I've been unable to reproduce it. NFS
server becomes unresponsive, clients hang, restarting nfs-kernel-server
doesn't improve matters; had to fully reboot the system to get things
running again.
