I remember discussing with Warner around the time of 4.5-STABLE that I had problems with interrupt routing on laptops. So I hope this is not a stupid question... The specific problem I had was that the OLDCARD code saw that the PCMCIA device I was trying to plug in did not allow irq 9 to be used as the function interrupt. The control interrupt of course was irq 9. I hacked OLDCARD somewhat to allow me to assign the function and control interrupts separately so I could get my PCMCIA smart card reader to work. I wonder if it's still possible to do something like this in these days of ACPI and cardbus, or is it no longer necessary (can I lie about which IRQ is routed to the pccard/isa device?) BMS
