but will disable /proc/acpi/wakeup. It'll also be impossible to load CONFIG_RTC_CMOS because CONFIG_RTC has grabbed the io ports, so it's not possible to use the new interface. This situation doesn't appear to be documented, which is less than ideal...
Actually, it seems to be worse than that - the PNP entry for my cmos clock doesn't appear to mention an irq, so the wakealarm entry doesn't work. I can happily wake it using the /proc/acpi/alarm interface. David, would you be happy with hardcoding the rtc-cmos IRQ to 8 on PCs if there's inadequate PNP information available? -- Matthew Garrett | mjg59@srcf.ucam.org
