Sad: IRQ 11 wedged with 3.1.11/3.1.12 on Dell Inspiron 5000

Hi. I have a peculiar problem with my Dell Inspiron 5000 running Redhat 6.1/kernel 2.1.14 (TI PCI-1225). I've tried running PCMCIA 3.1.11 and 3.1.12 with PNP on/off and I seem to be able to only use socket 0. Nothing happens when I insert a card in socket 1. The pcmcia drivers report that IRQ 11 is wedged and that the IRQ scan failed. Any help would be appreciated. Here is the log: Linux PCMCIA Card Services 3.1.12 kernel build: 2.2.14 #4 Tue Mar 7 23:26:06 EST 2000 options: [pci] [cardbus] [apm] PCI routing table version 1.0 at 0xfdf50 00:04.0 -> irq 11 00:04.1 -> irq 11 Intel PCIC probe: TI 1225 PCI-to-CardBus at slot 00:04, mem 0x68000000 host opts [0]: [ring] [serial pci & irq] [pci irq 11] [lat 168/32] [bus 32/34] host opts [1]: [ring] [serial pci & irq] [pci irq 11] [lat 168/32] [bus 35/37] PCI irq 11 seems to be wedged!

Anybody know what is going on? Thanks! -- Scott.

The wedged irq is not the main problem, anyway Re: Sad: IRQ 11 wedged with 3.1.11/3.1.12 on Dell Inspiron 5000 (Scott Porter) Date: 2000, Mar 10 From: David Hinds <dhinds@pcmcia.sourceforge.org>

The "PCI irq seems to be wedged!" message is telling you that a rogue device is sharing that PCI interrupt, and is holding that interrupt active, even though the driver for that device isn't loaded. So the PCMCIA drivers can't use the PCI interrupt: it will be continuously triggered until that rogue device (whatever it is) is told to stop. The wedged PCI interrupt is not really a problem, because the i82365 driver will automatically use ISA interrupts instead. It does not explain why one socket would not work. If you insert a card in socket 1, what does "cardctl status" say? You say "nothing happens", so I assume you don't hear any beeps at all. Does anything happen if you issue a "cardctl insert" command? After a cold boot, with no cards inserted, can you also send me the contents of /proc/bus/pccard/00/pci and /proc/bus/pccard/01/pci? -- Dave

I'm having similar problems.
