Actually, to be more specific:
1. boot with auto-mount, without noserverino
2. mplayer test
3. umount
4. bug
5. modify fstab, remount
6. mplayer test
7. leave mounted, run "reboot"
8. gets stuck with "Unmounting CIFS file systems: /mnt/ehs1 is not mounted"
1. boot with auto-mount, without noserverino
2. mplayer test
3. umount
4. bug
5. modify fstab, remount
6. mplayer test
7. umount
8. run "reboot"
9. gets past "Unmounting CIFS filesystems", but then doesn't
reach power down after throwing mount error 22 (invalid
argument). It just halts at "Restarting system now ...".
But anyway, I guess those are the weird consequences of the
earlier server bug.
