pcmcia and kernel 2.6 problem

Post #1 of 3 (461 views)

Hi, can someone enlighten me on how to exclude an IO range from the
kernel pcmcia modules (pcmcia_core, yenta_socket and ds) in kernel 2.6?
Ive tried reading the module code and am non the wiser.

It appears the kernel modules are totally different than the pcmcia_cs
modules and there's no way to pass arguments to them - at least they
dont understand or segfault when I try and modprobe them with
arguments. I want to do the equivalent of "exclude port 0x800-0x8ff"
that pcmcia_cs would put in /etc/pcmcia/config.opts which 2.6 does not
use.

The problem is that some dell laptops suffer from corrupt kernel space
and hang when you insert a cardbus card without this exclude.

Hi,

I edited '/etc/pcmcia/config.opts' and changed the line

'include port 0x100-0x4ff, port 0x800-0x8ff, port 0xc00-0xcff'

to
'include port 0x100-0x4ff, port 0xc00-0xcff'

If you read that config file, you will see a note to the effect that the
2.6 pcmcia modules do not use it.

I have made it work - sort of. You need to modprobe the pcmcia_core
mdsule manually, twice with the second time having the option
"pci=bioirq" The whole thing is really weird, undocumented and just
plain silly.
