Well, here's an oops, caused on my Thinkpad 760ED, 80Mb ram.

I can boot into 2.4.15-pre9 without problems, however I get the message
to "Try pci=biosirq"
This option works in 2.4.14 and prior.  [ As a side note, it still does not
fix the problem of my 3ccFE575CT pcmcia card being recognized as anything
but
IRQ0.  2.4.8mdk26 (yea, yeah) does see the card with IRQ=9. ]

adding the 'pci=biosirq' to my kernel boot command line causes an oops:

ksymoops 2.4.3 on i586 2.4.14.  Options used

I'd say that this crashes the system.. :-)

Happy Day of thanks to everybody on the list. Without all of us, the world
would not be as fun a place to be.
