I have just installed the 20050624-6.0-SEBSD-i386-miniinst.
When mounting a ext2 partition:
-su-2.05b# mount_ext2fs /dev/ad0s8 /mnt
-su-2.05b# ls /mnt
the system drops into db> like this:

Fatal trap 12: page fault while in kernel mode

I tried for an ext3 partition, the same thing happened. 
Is it a bug? or has it been discussed already? ( I am a complete newbie in 
this list.)
