Hi Trond,

I'm certain the problem is causing a crash on my machine.
When I am on the console and just do an umount the machine is okay
for about 2 seconds and then it crashes.  If I instead just try to do
/sbin/reboot then I see a big OOPS when the initscripts end up
unmounting the NFS filesystems, although it's hard to make sense
of it or write any info down at that point.

There is clearly something wrong but I'm starting to suspect it's
because the patch might not be appropriate for the kernels
that Kostas and I are using.  What version of the kernel (and
CITI patch, if applicable) are you making the patch against?
I'm using:

http://mirrors.kernel.org/fedora/core/updates/5/SRPMS/kernel-2.6.18-1.2200.fc5.src.rpm

Regards,
Paarvai
