RAIDframe swap problems?

[Chris Ross <cross+netbsd%distal.com@localhost>]

  I've been rebuilding a SS20 with netbsd-6.  I had an issue where it
panic'd when I tried to bring a second drive on as a spare for the
raidframe (RAID1), but I was able to reboot and perform that operation
again without incident.

  But, now that I think I have the whole thing completed, I see the
following when I boot:

Checking for core dump...
savecore: kvm_read: invalid address (0xf03e4e30)

  Is this something that is happening because I've configured a RAID1
as swap space?  I know this is known to work on sparc64 (and I'm doing
so on one), or is this just some other issue that popped up here and
isn't important?

  Thanks...  More of my boot log is attached below.
