Hello, bug-followup.
I've got very similar panic.
`csup' from local (located in same segment) cvsup server via gigabit
link and RAID5 (geom_raid5) synchronize newely-created array with 4
disks. csup writes on OTHER disk, not included in array.
No crashdump, because core was not saved: machine hangs up right after
panic message, without attempts to save dump or reboot. Crash dumps are
enabled and I got previous one (other bug), but in this case no dumps,
no reaction on keyboards, etc. Need to reboot with pwoer switch :(
