SubjectCIFS mount: 3.2.0-rc3 suspend crash
With CIFS mount present, suspend2ram seems to be failing on 3.2.0-rc3.
It may be similar to recent NFS suspend issues?

I have done couple of suspends, then did mount.cifs (at 555 seconds),
and then tried suspend again. The problem is easy to duplicate.

The hardware is a netbook Asus EeePC.
I guess will find out if:
- cifs for real 3.2 fixes the problem
- NFS fix for -rc4 work for CIFS as well...

Thanks, Woody
