2.2.12 (sparc) OOPS with serial console enabled

Sun SS20 which I administer via a serial console connection to a nearby i386
linux box, running a patched RedHat-5.1. Fresh compile of 2.2.12, with support
packages like mount and modutils duly upgraded.

SILO did it's thing, finds the new image, uncompresses it and boots on the
new kernel . . . it even gets as far as:

Turning on user and group quotas for local filesystems Setting clock: Sun Sep 5 18:09:11 PDT 1999 Enabling swap space. Initializing random number generator... zs_open ttyS0, tty overwrite. zs_open ttyS0, tty overwrite. zs_open ttyS0, tty overwrite.
[snip about 20-30 of these]
zs_open ttyS0, tty overwrite. zs_open ttyS0, tty overwrite. eth0: Carrier Lost, trying TPE

At this point the machine is ping-able, but does not seem to fire up any
services, and I don't see anything more which looks like a boot sequence on
the serial console. So I hit return on the serial link just to see if it would
still scroll.

The kernel OOPSed at this point. All kinds of nasty stuff written to the
console. I tried sending a few breaks via minicom, but they were useless,
eventually the screen just settled into a tight, seemingly uninterruptible
loop:

Unable to handle kernel paging request at virtual address 40001000 Unable to handle kernel paging request at virtual address 40001000 Unable to handle kernel paging request at virtual address 40001000 Unable to handle kernel paging request at virtual address 40001000
Unable to handle kernel paging request at virtual address 40001000 Unable to handle kernel paging request at virtual address 40001000

which scrolls endlessly, very rapidly.

Is this a known issue with kernel-2.2.12 on sparc hardware? I've seen one
other report in the archives.
