Subject: Re: PATCH : linux-2.6.35.4 drivers pcmcia cs.c

Hi,

indeed, on a IBM ThinkPad 770Z there seems to be some bug -- the CardBus
hardware doesn't tell the OS that it is CardBus capable. However, your
patch isn't correct -- it would enable CardBus on all PCMCIA bridges
unconditionally. Therefore, I'd need some more input for a proper patch:

1) Did CardBus cards work on any other kernel?

2) What's the output of "lspci -n -v"

3) What's the output of "sudo lspcmcia -vvv"

4) Are there any BIOS options you may toggle to enable CardBus?

Thanks & best wishes,

	Dominik
