Hi. Well, the subject gives you the problem. I've got some more info for you as well. Below is: kernel version, lspci information, relevant bits from /var/log/messages, and the oops run through ksymoops. I was getting similar problems during shutdown if the PCMCIA system shutdown before the USB system. I *suspect* it's a bug somewhere in the USB code, but have CC'd this message to the kind PCMCIA folks as well just in case)
If there's anything else you need, just ask (but I'm not a member of
this list, so perhaps email me directly. I'll post any reply to the
list)
Also, the USB card works perfectly under Linux (except for ejecting it),
so many thanks for that :)

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.
