Thank you. I am not going to use rtcwake on those 2 problematic laptops for anything real, but out of curiosity I will experiment a bit more.
One user wrote there that after a reboot, the wakeup time is still there after reboot, but the IRQ is disabled.
The "powertop" tool was not mentioned yet. A possible fix might be to use it to enable power management on the offending devices.
