Re: 2.5.75-mm1 nfs trouble

[Helge Hafting]

2.5.75mm1 has nfs trouble I don't see in 2.5.74mm3.

It works for a while, then all file operations
on the nfs mount gets stuck.

dmesg is then full of stuff like this:

At some point I managed to get my waiting processes "unstuck"
by "ifdown eth0" followed by "ifup eth0"  They all failed
with network unreachable and I saved files to a local disk.

I then tried some simple copying on the still
mounted nfs, and it got stuck again pretty fast.
I then rebooted into 2.5.74mm3 because I need to work.
I won't be able to test much until monday.

The machine is UP, and uses preempt.
The distribution is debian testing
The nfs mount uses the following options:
   rsize=8192,wsize=8192,user,noauto,hard,intr
