I've been seeing this panic on NetFinity 6000R since end of September.
-CURRENT is installed on a RAID partition, and the partition is controlled
by ips driver, so it's possible that the root of my problem is completely
different from yours, but anyway...

To reproduce it, enable dump device and create many files in a directory:

# mkdir foo; i=0; while :; do echo -n $i > foo/$i; i=$(($i + 1)); done

and go to bed and you'll get a kernel dump in the crash dump directory
in the next morning. At first I thought that the hard disk is damanged,
but the following dd command doesn't panic the machine, just fills up
the partition many times.
# while :; do dd if=/dev/zero of=BIG bs=1048576; done

With -CURRENT built from source as of D2003.10.21.00.00.00, I'm still
able to reproduce this panic, together with new one:
    panic: handle_written_inodeblock: live inodedep

Backtraces are available on request.
