Title:
Asus Prime B550 plus requires acpi=off which turns off SMP
Status in linux package in Ubuntu:
Confirmed
Bug description:
1) Ubuntu Release
No LSB modules are available.
Description: Ubuntu 24.04.2 LTS
Release: 24.04
2) Package version
6.8.0-54.56
3) What you expected to happen
I expected the system to be able to boot with ACPI.
4) What happened instead
The booting process got stuck halfway through (about when the console adjusts
it's resolution) if the kernel wasn't given the "acpi=off" parameter. However,
with this parameter, SMP doesn't work and my CPU is reduced to a single core
from 16 with HT.
I followed this guide for troubleshooting:
https://wiki.ubuntu.com/DebuggingACPI
The system refused to boot even with "acpi=ht".
