Public bug reported:
After upgrade to 22.04 machine freezes at boot.
Booting is possible in recovery mode.
If I do not select recovery, machine silently hangs.
Steps I've taken:
1) added acpi=off to the kernel params.
ACPI errors were visible scrolling past
1) Created and ran a boot-repair disk.
The only effect was to reduce the amount of visual feedback during the boot
process.
2) Successfully upgraded the BIOS
Current BIOS: B9450FA.313
