>Description:
When I mount a non-existing windows share name, (for example, I once mounted a share of //lsh2/c$ to /mnt, then lsh2 reboots, the "server" service of lsh2 doesn't start yet so the share c$ doesn't really exist, and /mnt is not umounted, then if I tries to mount //lsh2/c$ again to /mnt) freebsd automatically reboots. I cannot figure out what causes the problem.

>How-To-Repeat:
mount_smbfs //lsh2/c$ /mnt
reboot lsh2 without starting "server"(windows share) service
mount_smbfs //lsh2/c$ /mnt again
then freebsd reboots
