Three problems:

1. Panic, apparently having something to do with RAIDframe.

2. How to recover the RAID data after said panic.

3. I can't get savecore to do its thing and give me a core dump.

Problem 1:  Here's partial /var/log/messages output.  At the time of
the crash, I was copying a bunch of data onto a partition on raid1
(RAID 5) from an NFS mount.

=2E..and then it crashed.  The console had some message about RAIDframe
being unable to allocate a DAG.  I didn't write it down or get a
backtrace, because I knew it would make a core dump.  :-/

Problem 2:  I'd like to get raid1 back up again, but it won't
configure:

Now I could certainly force it to configure, in spite of the different
mod counters, but I'd rather wait on advice from persons more
knowledgeable.

Problem 3:  After reboot, I didn't get a core dump.  My fstab has the
line:
/dev/sd0b none swap dp 0 0
=2E..which means to use /dev/sd0b as the dump device -- don't know if
that has anything to do with it.  During boot, savecore runs before
swapctl, meaning that the swap partition hasn't been set yet when
savecore is run.  Looking through savecore.c, it appears that it reads
the kernel symbols to determine where the dump device is -- this seems
wrong; shouldn't it read fstab instead of or in addition to the
kernel?  At any rate, the ordering is definitely wrong.  After I've
booted and set the dump device, though:

gamera# swapctl -D /dev/sd0b
swapctl: setting dump device to /dev/sd0b
gamera# savecore -f -v -z /var/crash
dumplo =3D 0 (0 * 512)
savecore: no core dump

=2E..so I can't get a core dump or backtrace to help with problem number
1, above.

Any help in solving any of these three problems would be much
appreciated, and might even contribute to the other two.  :)
