Description
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.
Please post (or take a photo of) the output with a verbose boot ('v' from the loader menu).
As far as I can tell TSC synchronization gives no more output than just "TSC testing MP synchronization" if it succeeds.
verbose booting gives (the remaining lines that I can see):
Initialize MI interrupts
