Comment 12 for bug 574329

I, am experiencing this same exact issue. I believe the problem lies in the fact that the volume is having difficulty unmounting.

The logs above also indicate that with the error: "pam_mount(mount.c:68): umount.nfs: /home/USER: device is busy".

I am experiencing the same problem, only with CIFS. Somehow, pam_mount is not able to successfully unmount the share since some process is doing something.

Is there a way to force pam_mount to kill processes preventing logout?

**For me, this is a very high-severity, showstopping issue. I cannot roll out Ubuntu 10.04 to my development environment with this occurring.
