Hi,

a small update -- another way to trigger the problem:

I took the system up single-user, created a few users and
configured rc.conf to start sshd, so that I could log in
remotely.  That worked, but as soon as I typed "su<RET>", the
machine paniced:

NetBSD/sgimips (minnesota.urc.uninett.no) (console)

login: panic: cache error @ EPC 0x882b4098 ErrCtl 0x0 CacheErr 0xa0349c=
5d
panic: cache error @ EPC 0x882b049c ErrCtl 0x0 CacheErr 0xa03b1f21
panic: cache error @ EPC 0x882b04c0 ErrCtl 0x0 CacheErr 0xa03b1f31

                bdslot: nop
db> =


882b0428 appears to be in cpu_Debugger() which starts at 882b0424,
0x882b4098 is in trap() which starts at 882b4054, and 0x882b049c is
in db_set_ddb_regs() which starts at 882b0430.  Not much help there,
and "trace" doesn't work:

db> tracepanic: cache error @ EPC 0x881d22dc ErrCtl 0x0 CacheErr 0xa032=
