SubjectRe: 2.4.20-pre2-ac2 pcmcia panic + OOPS


finally I was able to catch the oops related to this problem.

ksymoops 2.4.3 on i586 2.4.20-pre2-ac2. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.20-pre2-ac2/ (default)
-m /usr/src/linux/ (default)

Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.

> 2.4.20-pre2-ac2 with pcmcia-cs-3.2.1 locks the box and makes 2 LEDs blink.
> 2.4.19-ac4 with pcmcia-cs-3.1.33 shows the same symptoms.
> 2.4.19-ac4 with pcmcia-cs-3.1.34 does not lock up, but also does not work.
> Kernel pcmcia never worked on this box, so I had to resort to the version of
