Hi,

Latest patch (this one) applied to linux-3.1-rc2 works, at least it mounted
this time and did not instantly crash the kernel!

I also tried the hostname again (and it did not crash the kernel, but it 
failed to mount).

Used the IP and it mounted successfully:
//10.0.0.11/x          28T  5.0T   23T  19% /mnt
//10.0.0.11/y          19T  1.2T   18T   7% /mnt2

It has not crashed yet (which is good), I'll apply this patch to my
production machine and test taking backups of this data and let you know
if it crashes again, thanks!

Justin.
