--- Comment #2 from Kirk McKusick <mckusick@FreeBSD.org> ---
What were the details on the filesystem in question (df information, and
ideally the first 100 lines of dumpfs of the filesystem). Were you running =
it
using soft updates or journalled soft updates?

Were there any I/O errors reported for the drive in the system logs.

Did you run fsck on it after the crash, and if so what if any errors did it
report/fix?

If you were running your filesystem with journalled soft updates, please try
running a full fsck check on it (fsck -f). A drawback of any journalling
filesystem is that it only checks things that it thinks might be wrong. If a
disk error occurs, then unexpected data can get corrupted and a journal
rollback will not fix it. Only a full check of the filesystem will do so. A=
nd
as long as it is not fixed, you will keep tripping over the same error/panic
until you do fix it.
