Hi,
now I switched to linux-2.3.99-pre7-9 and pcmcia-cs.10-May-00.tar.gz
and I deactivated APIC.
During bootup everything looks IMHO fine:
May 11 12:38:34 frodo kernel: Intel PCIC probe:
May 11 12:38:34 frodo kernel: Intel i82365sl DF ISA-to-PCMCIA at port

May 11 12:38:34 frodo kernel: ISA irqs (scanned) = 3,4,7,10,11 polling

May 11 12:38:34 frodo kernel: cs: IO port probe 0x1000-0x17ff: clean.

May 11 12:38:34 frodo kernel: cs: IO port probe 0x0a00-0x0aff: clean.
except the timeout in the end:
May 11 12:38:37 frodo kernel: cs: socket 0 timed out during reset
dump_pirq output:

Ok, what else can I do to help debugging this?
I don't have any clue about device drivers and kernel hacking..
Cheers, Alex
