Can you try booting the original tickless (NO_HZ) configuration without the "nohpet" boot option and wait >= 5 mins after resume to see whether your machine comes to life afterall. The 5min means we want to wait until the 32-bit HPET counter overflows to see whether the timer gets programmed with an event in the past right after resume. Thanks. -- Regards/Gruss, Boris.
