>Description:
I login as root
switch to bash shell
i mount a smbfs file system on to /mnt using command "mount -t smbfs //192.168.0.20/myshare /mnt
i get a password prompt, on which i enter password
system returns to # prompt
try a cd /mnt , get a 'permission denied'
try a "umount /mnt"
System immediately reboots without warning or wait.
try to cd /mnt - gave permission denied
<nataraj> when umount /mnt, the system reboots
<nataraj> shocking! never has it happened on Linux or Freebsd

Can you apply rev 1.88 of src/sys/fs/smbfs/smbfs_vfsops.c and see if
that helps? Or simply try a NetBSD 5.1-RC1 kernel.
(run "cvs up -j1.87 -j1.88 smbfs_vfsops.c" in src/sys/fs/smbfs)
If not, please provide more information about what happens. If necessary,
"sysctl -w ddb.onpanic=1" and run the problematic commands directly
from console.
