2.6.30-gentoo-r6
mount.cifs version: 1.12

The server is an Apple Airport Extreme Base Station with two attached
external drives.  I have no trouble mounting them from Linux 2.6.30 or
from Windows machines or Macs.

Here's what I get in dmesg when I unmount and remount the fs under
2.6.30 when debugging is enabled:

When 2.6.31 boots, ostensibly, it acts as though it was mounted, but I
do see this in dmesg:

 CIFS VFS: Error connecting to socket. Aborting operation
 CIFS VFS: cifs_mount failed w/return code = -111

 CIFS VFS: cifs_mount failed w/return code = -111

Does this tell you anything useful?  I could have some other kernel
parameter wrong, but I couldn't begin to imagine what it might be.

Thanks.
