Random hangs on 5.0 on R5000 Challenge S

[George Harvey <fr30%dial.pipex.com@localhost>]

Hi,

I have a R5000 Challenge S which has been running NetBSD 4.0 quite
happily. Today I upgraded it to 5.0 and now I'm seeing random hangs.

The first one happened during the upgrade process itself when
postinstall hung while performing the cleanups after installing base and
etc. Hitting ctrl-C broke out of postinstall and allowed the rest of the
upgrade to continue. On rebooting from local disk, what I now see are
hangs at various places while running the rc script. For example, I've
seen it hang in fsck, mount, rm, sshd and getty. Sometimes I can use
ctrl-C to abort the hung process and it will continue on for a few steps
then hang somewhere else. Kernel boot messages are included below, if
there is any other info I can provide that would help to find the
problem, let me know.

George
