5.0_RC2 panics on qt0

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

I've just updated from 5.0_BETA to 5.0_RC2 on my VAX 4000/500A. The
update process went through smoothly but on rebooting I get:

qt0 at uba0 csr 174440 vec 764 ipl 17
panic: Segv in kernel mode: pc 801fcc25 addr 1c
Stopped in pid 0.1 (system) at netbsd:trap+0x697: nop

I suspect this is the same problem I saw with with the beta release and
which was fixed by the patch suggested by Havard Eidnes. I've downloaded
the source tarballs and I'll do a kernel build tonight (it will be a
native build so may take a while...)
