The problem with suspend actually turned out to be because the APIC is unconditionally enabled _before_ the command line is scanned and the 'noapic' option is detected. The noapic option, however, does have the effect of preventing the registration of the power management code :) Booting with 'apic' makes the thing take some time to suspend, and then it reboots instead of resuming. That may be your case (b). I put printk in the apic suspend and resume functions and neither of them seem to appear. -- dwmw2
