PCMCIA no longer works after upgrading to 2.4.22 kernel in RH 9.

machine is SONY C1MW laptop (Picturebook) with Transmeta Crusoe processor.

While compliling the kernel, i made only three changes:
1. added native support for Crusoe processor
2. Removed APM
3. Added (as modules) all ACPI functions.

The reason for #2 is that I saw in the xconfig "help" for APM is that APM isn't needed if ACPI is being used, and it can interfere with ACPI if APM is loaded. Someone tell me if I'm wrong on this?

While booting, the (known good) cards I've tried ARE recognized and thier respective drivers ARE loaded.

the only real problem I see while booting is this message:

"orinoco_cs: RequestIRQ: Resource in use"

My theory:
Since ACPI handles all the irq's, etc, is it getting stepped on by something else?

Unfortunately, I'm away from the machine right now, but will be able to post whatever logs or command outputs needed later today.

On the plus side, the machine is noticably faster with native processor support enabled.

Anyone got any ideas?

Your problem sounds slightly different than mine but this is what I had to do after PCMICA stopped working after I recompiled my kernel:

Apparently there's a PCMCIA BUG in RedHat 9 that builds a bogus directory of symlinks in '/lib/modules/`uname -r`/pcmcia' I removed the directory and everything now works perfectly.

I saw your other post concerning removing the PCMCIA dir in the kernel dir.... did this and still no-go. thank you for replying, though.

After some more tinkering, I believe I've discovered the problem...

It appears as though ACPI is controlling all the IRQ's, and most of the ancillary stuff (nic, card services, USB, firewire, etc..) are getting lumped onto IRQ 9. Not unusual, in fact pretty ordinary. BUT, "something" in ACPI is causing it to not controll things correctly. The only thing on interrupt 9 that works is the nic (a realtek 8139)

oh, well, not to worry. gave up on that problem and just went back to RH kernel 2.4.20-20.9

Now plunged into Fedora test3 on a different machine, new problem, so new post...

Ah, okay, sorry speedbump. When all you have is a hammer everything looks like a nail...
