The multipath tools are installed -- but I don't think they're required. The
selected packages for this system came from a package list on an etch system
which this machine is replacing.
> Why are you not using mdadm for multipaths?
Per the above, multipaths should not be required for this configuration.
Additionally, I didn't make a concious selection of one over the other,
so unfortunately I can't give you a helpful answer to that. -- Should
I simply attempt to remove the multipaths-related packages?
> Do you have the dmraid package installed?
No.

I can certainly do that... however, enabling 'debug' on the kernel boot line
affects the timing enough that the problem doesn't occur any more. Do you still
want the debug log?

Thank you for the information on HOMEHOST ... now the last half of that UUID
being the same makes sense.
I have copied the requested output from /usr/share/bug/mdadm/script
below -- I will try to get to the 'strace' testing within the
next day... The segfault in mdadm does not occur every time, so it
may be a bit harder to catch.
