I think that the root problem is actually memory corruption from the
amr-cam module. I haven't been able to nail it down further, though.
However, this module is entirely optional and isn't used for anything
in the base system (it's only useful if you hook up a cdrom or tape
drive to your RAID card), so I've disabled it CVS HEAD and RELENG_6
until I can fix it for good.
