Possibly, but then we did use to have all interrupts disabled at some stage before going to suspend_late anyway no ? So it shouldn't make a big difference. The VIA interrupt must not be HW masked in the PIC on some machines because it's the wakeup source, so we may have to force re-enable it since it can be lazy-disabled, but those aren't the machines with the trackpad problem so I think I'll need to have a closer look at what's going on and get my head around it. Haven't had a chance yet, hopefully today or tomorrow. Ben.
