2.4.17-pre8-ben0: kernel oops using pcmcia services

[Ralf Weidemann]

I get the below kernel oops after I put my cisco aironet pcmcia card into
the external slot on my tibook. Kernel bug or wrong setup ? While loading
the airo_cs module per hand I get no oops.

Looks like it tried to ioremap an ISA memory address, bad bad bad...

Either your memory options in config.opts is wrong or that driver
has a bug.

Ben.

Hmm.. don't know. Here is my config.opts, maybe you could take a look
on it ?

Thanks

First make sure the memory resources you use are available
in /proc/iomem

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

Those should be ok

>include memory 0xc0000-0xfffff

This one is wrong (this is in the middle of RAM !)

>include memory 0xa0000000-0xa0ffffff, memory 0x60000000-0x60ffffff

Hrm...  the second one is wrong at least.

try

include memory 0xa1000000-0xa1ffffff, I think this one is available
on your machine.

Remove the above exclude, they don't make sense on pmacs

Ben.
