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.)
