[linux-cifs-client] cifs mounts not working after software suspend (swsusp)

[Robert Freund]

Hi,

I'm running kernel 2.6.11. Filesystems exported by a remote samba machine and 
mounted using cifs will not work after resuming my machine from a software 
suspend 2 / swsusp 2 / hibernate state (functionality you get with patches 
from http://suspend2.net ). Unfortunately I can't get swusp1 to work here, it 
always fails when I try to suspend, so I can't test if the problem exists 
there, too.

After resuming, there are no new kernel messages. Doing an "ls" of the 
mountpoint results in a couple of messages like this one:

 CIFS VFS: Error 0xfffffffb or on cifs_get_inode_info in lookup

and "ls" tells me: "Input/output error"

Doing a "mount -o remount /mnt/mountpoint" returns: "mountpoint does not 
exist" (and no kernel messages).

"umount /mnt/mountpoint" seems to correctly unmount the cifs mount, but I get 
this kernel message:

 CIFS VFS: cifs_umount failed with return code -5

After umounting I can mount the share without problems again.

Can anyone confirm this with (vanilla) software-suspend-1? Does anyone have an 
idea what can be done about it? Is this even the the right place to ask?

I'm not subscribed to the list, so please cc me. Thanks.

Robert
