I can kill it on a fresh 2.1.123 with only the memory patch applied, simply by
trying make -j clean; make -j dep; make -j zlilo; make -j modules; make -j
modules_install. It seems to die in make dep.

Aiee, killing interrupt handler
Kernel panic: Attempted to kill the idle task!
In swapper task - not syncing

No kernel messages of any kind regarding this, however, the syslog contains
"Symbol table has incorrect version number" every time I start the computer
dating back from my first kernel upgrade from Slackware 3.5. I think this would
make ksymoops useless. I can't get it to work anyway -- it says "Cannot read
eip address from EIP: line. Is this a valid oops file?" when fed the oops in
the exact formatting above, which I think is wrong -- I had to copy by hand.

I'm running 32 MB, 75MB swap, a SMP kernel on a non-SMP board, PPro 180, Intel
VS440FX mobo.

Previously doing this failed silently (I think) when all memory and swap was
used up.
