>Environment:
System: NetBSD tesseract.neutralgood.org 1.6 NetBSD 1.6 (TESSERACT) #35: Mon Oct 28 22:44:20 EST 2002 kpn@neutralgood.org:/local/kernel/compile/TESSERACT alpha
Architecture: alpha
Machine: alpha
>Description:
I got up this morning to find that my AXPpci33 had crashed. From looking
at the dmesg I'd guess that there was some sort of network problem that
blew up NFS (NFS that was mounted through the automounter, even). 

I do have a crash dump if it is needed.

From my dmesg:

setclock: 50/11/8/1/57/24
nfs server tome:/local: not responding
nfs server tome:/usr: not responding
nfs server tome:/var: not responding

CPU 0: fatal kernel trap:

CPU 0    trap entry = 0x4 (unaligned access fault)

CPU 0    a1         = 0x28
CPU 0    a2         = 0x3
