Hello!

I just tried your 2.4.19-low-latency patch on a stock 2.4.19 kernel and
my box oopses when I manually remove my PCMCIA modem.  I know I should
probably use cardctl eject, but I guess the kernel should not oops in
any case and other PCMCIA cards do not have that problem.

I spent the whole day trying to debug the oops because minicom and my
serial console do not seem to want to get along.  I suspect a hardware
bug somewhere, I always got garbled output.  I managed to capture the
output once but was not able to reproduce the correct settings again, so
apologies if I cannot provide the correct information.

Back to topic: I figured you might be interested in this, so I am
sending you the output of ksymoops.  If you need more information I will
be more than happy to provide it.
Thanks for your work on the Linux kernel.
Regards

Diego Biurrun
