Bug#330424: kernel-image-2.6.8-2-686: yenta_socket hangs or disabled irq
Package: kernel-image-2.6.8-2-686
Version: 2.6.8-16
Severity: important
Hello,
The problem here is that if I configure the bios so that PINA to PIND use IRQ11, wich is the BIOS default, yenta_socket, loaded by the pcmcia_cs package or by hand, seems to load fine, here is the relevant part of dmesg:
Linux Kernel Card Services
options: [pci] [cardbus] [pm]
PCI: Found IRQ 11 for device 0000:00:02.0
PCI: Sharing IRQ 11 with 0000:00:05.0

PCI: Found IRQ 11 for device 0000:00:02.1

Yenta: ISA IRQ mask 0x06b8, PCI irq 11
Socket status: 30000006
But inserting a card (here an USB 2.0 / Firewire Combo card) hangs the system, until I remove it. I tried to compile the kernel with pcmcia debugging option enabled, but there is nothing in dmesg or kernel.log, never. When I remove the card the system "lives" again.
Now if I assign different IRQS in the BIOS, I'll get the famous "IRQ(choose_whatever_here): nobody cared" message, followed by "disabling IRQ(whatever)".
This happens on a thinkpad a20p, with a TI1450 cardbus controller, the relevant part of lspci -v is:

As a test I tried to plug in another disk, install windows 2000 on it, plug the pcmcia card in, and everything works fine. The both slots get IRQ 09 assigned, the same
memory window as in debian, and for I/O window I don't know, my little knowledge is ending here it's not written in the same format.
