I just tried booting off the FreeBSD 5.2 install disc on my system. No
crash on removal, but I do get the same three repeating error messages
and still no device appears in /dev. Then I tried this boot disc on an
Intel (440BX) machine. No error messages, but still no /dev entry. I
must be seeing both an old VIA-related 4.X bug and a newer 5.X bug where
the device doesn't appear, which recently can also trigger a crash.
Did you say that you can mount the filesystem, and it freezes when you
unmount it? What happens if you just unplug the device after plugging
it in? I don't have a way to mount it, but unplugging the device
crashes my system.
