HELP!

Here's my config:

Mac IIcx 
Farallon Ethernet NIC (which I have used with NetBSD 1.1)
32 megs RAM 
MacOS 7.5.3

PROBLEM:

I ran mkfs on the a/ux partiton (a partition I made with Disk Manager
Mac 4.02). mkfs ran fine, as it has in the past. Then I run the
installer, and it eventually crashes the entire machine with a bus
error. 

Here is what the Installer console said:

sd0 at scsi ID 6
Partition read, SCSI ID = 6
Mounting Partition 'A' as /
failed mountfs ( ) , error 22
error mounting root
mount root. : undefined error : 0

Then it gives me the good old bus error.

What should I do? (sorry to sound like a lamer again)
