While at the IF, we had a system that wouldn't recognize the IRQ of the cardbus "controller." (And, as a consequence, Linux set its IRQ to IRQ 0.) We were trying to get a wireless NIC working, but the modules (y-something module and all other modules that depend on it) wouldn't load. The error message was:
PCI: No IRQ known for interrupt pin A of device 00:0a.0. Please try using pci=biosirq. or something like that. The obvious solution was to assign an IRQ to the PCI device from the BIOS, but the BIOS was a bare-bone BIOS that had no PCI options at all. We tried passing pci=biosirq to the kernel at boot but that just froze the system during PCI discovery. So we were thinking -- We can get a newer BIOS that knows PCI, which we couldn't find any. Another option was to force-assign an IRQ to the PCI device (by its device ID) but nobody knew how to do it. Some web-browsing shows that ACPI has some PCI IRQ rerouting thing happening but I can't find any more information about what that is or how to use it. Sooooooooo... Does anyone know how to force-assign an IRQ to PCI devices? Would that even work? Thanks in adv! -Mark PS: The Installfest went as usual (mostly working except certain hardware,) except for one system that came in with a wireless NIC that nobody could get to work. (This is a different system than the one I'm discussing above.) -- Mark K.
