Bug #3087: Acer TravelMate Spin B hangs in TSC testing synchronization..

I am running DragonFly 5.0.0-RELEASE on an Acer TravelMate Spin B (Intel N3450 @ 1.10 GHz) laptop.

When booting, it shows:

    TSC invariant clock: 1094436275 Hz
    lapic: TSC Deadline Mode: shift 0, frequency 1094436275 Hz
    srat_probe: can't locate SRAT
    Initialize MI interrupts
    TSC testing synchronization ...

and then it loops/hangs forever. Any help appreciated.
