As I reported on the "Vinum status" thread a few days ago, gvinum is not
very graceful when a disc disappears/dies in a RAID-5 array during
operation. The machine I was testing this on was an SMP machine, but when I
recompiled the kernel with ddb/kdb support I removed "option SMP" just to
take that out of the equation.

The system:
-----------
ASUS P2B-DS mobo, 2 x P3/700, 1GB ECC RAM, latest BIOS (1014, beta 003)
Some old 9GB ATA disc for the OS on the onboard 440BX UDMA33 chipset
4 x 120GB Maxtor SATA discs on a HighPoint RocketRAID 1540 (HPT374 chipset)
The 4 120GB discs were put together in a RAID-5 array using "classic" vinum
(so they have overlapping slices and VINUM slicetypes).
Kernel/userland dated: 2004.08.10.21.00.00 (no CFLAGS/COPTFLAGS, but I use
"CPUTYPE?=p3")
gvinum started from /boot/loader.conf (geom_vinum_load="YES")

The crash:
----------
Stop all non-essential processes (to protect against unnecessary file
corruption, normally I've got Apache+PHP4+MySQL running among other things).
Set up one process to write to the RAID-5 array (I have used a simple sftp
to another machine, pulling down big files).
Pull one of the SATA-cables.
*boom*


I have a vmcore dump and a kernel.debug, but I can't seem to get gdb53 to do
what I want (not very familiar with gdb), so here's the output I took down
on paper from within ddb. The first 5 lines are exactly what I would expect
to happen (and what "classic" vinum also did), but then something goes wrong
and the machine page-faults:

ad8: TIMEOUT - READ_DMA retrying (2 retries left) LBA = 196849498
ad8: WARNING - removed from configuration
gvinum: lost drive 'vinumdrive2'

Attached is the kernel config file and the dmesg. Let me know if there is
anything you want me to do with gdb to further track this down. I could
probably even arrange for a guest account on this machine if someone wants
to take a closer look at the vmcore file.
