>Release:        4.1.1-RELEASE for alpha
>Organization:
Mind over Matter
>Environment:
never got to uname -a , but hardware specs are:
233Mhz AXPpci33, only 64Mb ram, 256kb cache, realtek8139 nic, vanilla
scsi and ide harddisk (1 each).
SRM console version 1.6, OSF Palcode 0x100090002012d
It ran linux fine, and started the installation of FreeBSD 3.4 fine
(that crashed later, when installing the first packages, but that's another bug report)
the point is: the hardware is very likely to be ok.
>Description:
When booting from floppy (srm console: boot dva0) the bootstrap
loaders get as far as starting the kernel and then: 

Preloaded elf kernel "kernel" at 0xfffffc0000922000
Preloaded mfs_root "/mfsroot: at 0xfffffc00009220b0
md0: Preloaded image <mfsroot> 2949120 bytes at 0xfffffc000064e0a0
md1: Malloc disk
lca0: <21066 Core Logic chipset>

fatal kernel trap:
	trap entry = 0x2 (memory management fault)
	a0	   = 0x1
	a1	   = 0x0
	pc	   = 0xfffffc0000545690
	ra	   = 0xfffffc000054559c
	curproc	   = 0xfffffc00006467b0
		pid = 0, comm = swapper

panic: trap
Uptime: 0s
Automatic reboot in 15 seconds -.....


>How-To-Repeat:
