I've just installed release 3.0 and it panics with the following messages:

Oct 29 16:08:48 localhost mach: unexpected kernel page fault failure
Oct 29 16:08:48 localhost mach: trap: type 0x410 fcode 5 rw 3 faultaddr 0x3fffda0
Oct 29 16:08:48 localhost mach: trap: pc 0x405ea1a sp 0x3fffdcc sr 0x2004

Oct 29 16:08:48 localhost mach: last fp 0x3fffdd8
Oct 29 16:08:48 localhost mach: panic: (Cpu 0) MMU invalid descriptor during table walk

The 3.0 installation seemed to work fine. The panic occurs a few seconds
after the "reboot complete" message. The disk I'm using is a brand new
Fujitsu 2624. Prior to the installation, I did a /usr/etc/builddisk on
this new disk. I'm running 2.0 on a 24MB 25MHz Cube. My default boot disk
is still my old 2.0 disk, so to boot from the 3.0 disk I interrupt the
boot and type "bsd -a" and then "sd1" when prompted for the boot disk. The
/etc/fstab has been set up OK. There's 150 MB free on the new disk.

Anyone know what can be causing the panic?
