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.
