Kernel Panic related to mount/umount

[Ivo Vachkov]

Hello all,

Last night I discovered by mistake following problem. Commands

mount_cd9660 /dev/acd0 /cdrom
mount_cd9660 /dev/acd0 /cdrom
umount /cdrom
ls -al /cdrom

lead to kernel panic on my laptop. I use FreeBSD-CURRENT, source
updated for the last time on Dec. 02, 2007. I update it since FreeBSD
6.

Thank you very much in advance.
