BUG: soft lockup detected on CPU#1!

["brendan powers" <brendan0powers@gmail.com>]

Hello, i'm running debin sarge(3.1) with kernel 2.6.16.7 and came
across this kernel oops. It locked up shortly afterwords. Its a
terminal server so there is a lot of different things going on so i'm
not sure exactly what caused this to happen. Anyone have any ideas?

Here is the log of what happened.

CIFS VFS: Error 0xfffffff3 on cifs_get_inode_info in lookup of \.directory
