[Bug 600565] [NEW] cifs hangs with "Server not responding"

Ubuntu 10.04 with uname -a: Linux ubuntu 2.6.32-23-generic-pae
#37-Ubuntu SMP Fri Jun 11 09:26:55 UTC 2010 i686 GNU/Linux

grep cifs fstab:
//10.0.0.84/ControlPanel        /home/jamesg/ControlPanel       cifs    noauto,username=jgreen 0       0

The ControlPanel share is a PHP project. I can read the files within it
over the CIFS share without any problem using less, vim, etc. However,
when I run 'phpunit' nothing happens except on the console where I see:

CIFS VFS: Server not responding
CIFS VFS: No response for cmd 50 for mid 1234

Repeat the No response line every few seconds. If I ctrl+C the phpunit
execution it takes a few seconds to quit.

The Ubuntu machine is actually a vmware-server instance. The vmware
-server runs in the WinXP machine that hosts the samba share, so that
CIFS link is running over a vmware local network. This link should be
very fast and was running perfectly fine prior to this new kernel being
installed this morning. I'm about to test with the previous kernel.

I have also tried with OplockEnabled set to zero without change.
Sometimes (not always) if I try to access the web site itself on the
Ubuntu VM, it works, sometimes it never responds.
