Public bug reported: 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". ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Attachment added: "output of uname -a" https://bugs.launchpad.net/bugs/2100778/+attachment/5861852/+files/uname-output.txt ** Description changed: - 1) Ubuntu Release No LSB modules are available.
