Interrupt: pin A routed to IRQ 0 that's not going to work Well, yes, I know that with IRQ 0 this will not work. The question is how to get some saner IRQ assignment. :-) PCI IRQ's are asssigned by the bios...... so a bios upgrade ? I too have the same problem. I too have tried all the above and can verify it ain't workin. Hi... i've tried Debian 3.0 and all works fine. IRQ is correctly assigned and wireless pc-card work very well :-/ IMHO this bug can be solved without a bios upgrade Just confirmed this is still a problem with RHEL3 ES (though I haven't tried the first update CD that recently came) |
Description of problem: On Acer Travelmate 230 one can find the following in 'dmesg': Linux Kernel Card Services 3.1.22 options: [pci] [cardbus] [pm] PCI: No IRQ known for interrupt pin A of device 02:09.0. Please try using pci=biosirq. ds: no socket drivers loaded! "pci=biosirq" does not help at all and 'ds' and 'yenta_socket' fail to load. 'modprobe' ends up, not very surprinsingly, with init_module: No such device Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters. OTOH this laptop has a widely used OZ6912 Cardbus Controller, which is specifically listed as supported in PCMCIA-HOWTO, and one can find a confirmation of that in many places on the net. Also current Knoppix kernel when startd on the machine in question at least loads 'yenta_socket' and 'ds' modules. It is difficult to say for me how this works as at this moment I do not have any cards to check. :-) Probably not at this moment as IRQ assigned is still 0. This may something to do with the fact that this laptop supports, and apparently assumes, ACPI for its various functions. It can be seen in "e820 map": .............. BIOS-e820: 000000000f760000 - 000000000f76e000 (ACPI data) BIOS-e820: 000000000f76e000 - 000000000f780000 (ACPI NVS) ........ but ACPI is turned off in a kernel configuration.
