I was mucking about with PC Cards last night and got some strange results,
I was able to work around the problems, but thought I would ask about them,
just in case.
My environment:
4.1.1-Stable (cvsuped yesterday)
Sony Vaio PCG-Z505S
relevant dmesg output:
pcic-pci0: <Ricoh RL5C475 PCI-CardBus Bridge> at device 10.0 on pci0
pcic0: <Intel i82365> at port 0x3e0 iomem 0xd0000 irq 10 on isa0
pcic0: management irq 10
pccard0: <PC Card bus -- kludge version> on pcic0
Strangeness #1
If I configure pcic0 for polling mode (as is now the recommended config),
my machine freezes when I insert a card into the slot. It _might_ unfreeze
when I remove the card, but then again, maybe not. When I set it to irq 10,
it works properly.
Strangeness #2
I just got a IBM Data/Fax Modem 56K (made by USR/3Com/Megahertz - really a
XJ5560) from eBay... the modem is recognized in the default pccard.conf
with the entry:
# IBM 56k PCCCARD modem
card "IBM" "56K PC Card Modem"
config 0x22 "sio" ?
pccardd logs that it has found a matching entry and then the kernel
panics. Yikes!
If I comment out these lines and let the "generic" modem entry handle it,
all is fine.
Strangeness #3
I noticed that dumpcis has some problems with this card:
Code 128 not found
Code 128 not found
code Unknown ignored
Code 131 not found
Code 131 not found
code Unknown ignored
Configuration data for card in slot 0
Tuple #1, code = 0x1 (Common memory descriptor), length = 3
...
Is that sort of output considered normal? If not, is my card at fault or is
it something strange in the PC Card code? It seems harmless, the modem
seems to work fine.

Nothing spoils fun like finding out it builds character.
