My laptop nfs mounts /devel directory from my workstation using autofs with
-soft,intr over vpn tunnel.  My laptop suspends/resumes often and connects to
all different networks - basically I use whatever AP available.  It usually
works great.  However, I just had a very weird hang.

The network I was on right before was very unreliable.  It was slow and lost
lots of packets.  I tried to copy a rather large file (a few megs) over it and
then I had to move so I closed my laptop (it suspends) and moved to another
location.

At the new location, I had a good connection.  I brought VPN up and everything
looked fine.  I could cd into /devel and ls files.  However, all accesses to
file contents hang.  cp, mv, file, less - anything which accesses the file
content got hang; however, listing and stat'ing files worked just fine.  I
switched to single mode and did sysrq showtasks.  I'm attaching it here.

Note that this is the first time this happened in a few months so I don't think
I'll be able to reproduce it easily.

Thanks.
