I got a panic while performing a repetitive 'fdisk -BI aacd0', where aacd0 is a disk on aac0: . This means that the command was issued after filesystems were already created on aacd (after the first fdisk -BI aacd0 iteration), and are in umount'ed state. This is on 7.2-R, amd64. Config is a GENERIC plus ddb, carp, ipfw, quota.
