Having CONFIG_PCMCIA=y and CONFIG_YENTA=y solved this particular
problem for me, as I liked ACPI too much to give it up.




Well, seems like ACPI is still a show stopper.  I rebuilt the kernel
without APM and with ACPI.  Building PCMCIA and YENTA static did solve
the problem of it hanging when starting pcmcia, but still have other
problems.

At boot I see:

    PCI: Enabling device 0000:00:0b.0 (0000 -> 0002)
    ACPI: No IRQ known for interrupt pin A of device 0000:00:0b.0 - using IRQ 255
    Yenta: CardBus bridge found at 0000:00:0b.0 [1179:0001]
    Yenta: ISA IRQ mask 0x0cb8, PCI irq 0

I'm just guessing, but it looks like CardBus isn't going to be able to
generate interrupts.

Then when my pcmcia card tries to install I get:

Apr 20 22:45:43 localhost cardmgr[345]: socket 1: Intersil PRISM2 11 Mbps Wireless Adapter
Apr 20 22:45:43 localhost cardmgr[345]: executing: 'modprobe orinoco_cs'
Apr 20 22:45:43 localhost kernel: orinoco.c 0.13e (David Gibson <hermes@gibson.dropbear.id.au> and others)
Apr 20 22:45:43 localhost kernel: orinoco_cs.c 0.13e (David Gibson <hermes@gibson.dropbear.id.au> and others)
Apr 20 22:45:43 localhost kernel: orinoco_cs: RequestIRQ: Resource in use
Apr 20 22:45:44 localhost cardmgr[345]: get dev info on socket 1 failed: Resource temporarily unavailable

And then removing the PCMCIA card the system hangs hard.


Weird, I have the same setup, but haven't seen a hang like that.
