SubjectRe: 2.5/2.6 PCMCIA Issues
Ok, more data points.

- Zwane Mwaikambo tried enabling yenta + i82365 + pnp on his machine.
The boot messages for PCMCIA were:

Linux Kernel Card Services 3.1.22
options: [pci] [cardbus] [pm]
...
ti113x: Routing card interrupts to PCI
Yenta IRQ list 0000, PCI irq9
Socket status: 30000006
Intel PCIC probe: not found.

As you can see, the PCIC probe didn't find any PNP devices. No
problems were noticed.

- I've just tried modular PCMCIA, inserting both yenta and i82365 on
an (arm) machine, obviously without PNP here...

Linux Kernel Card Services 3.1.22
options: [pci] [cardbus]
irq 21: nobody cared
Yenta IRQ list 0000, PCI irq21
Socket status: 30000007
irq 22: nobody cared
Yenta IRQ list 0000, PCI irq22
Socket status: 30000811
Intel PCIC probe: <7>PCI: master abort, pc=0xbf020818
PCI: master abort, pc=0xbf020818
PCI: master abort, pc=0xbf020818
not found.

Again, no PNP activity as expected, and no undesirable side effects
caused by inserting and removing PCMCIA cards. (the master aborts
come from attempting to access 0x3e0/1 and having nothing on the PCI
bus to claim it... yes, not even an ISA bridge...)

Could the problem be PNP related? I don't see much material change in
the PNP layer between 2.5.70 and 2.5.71 though.

Can other people try the CONFIG_YENTA=y, CONFIG_I82365=y, CONFIG_PNP=y
and report their results (in particular the dmesg from boot, and whether
the machine locks when they insert a card _after_ boot.)
