Public bug reported:
Release: Ubuntu 24.04.3 LTS
Package Version: N/A or at least unsure. the faulty module is a kernel
driver which controls the subsystem "Acer Incorporated [ALI]
ACP/ACP3X/ACP6x Audio Coprocessor" on the PCI device "Advanced Micro
Devices [AMD] AMD ACP/ACP3X/ACP6x Audio Coprocessor (rev 63)"
What happened: The system reliably kernel panics on boot, usually about 4-5
seconds in, with a kernel panic that's abrupt enough that neither journalctl or
kdump-tools are able to reliably record information about it, meaning I was
only able to capture it with a photograph of the kmsg panic screen.
What I expected: System does not kernel panic on boot.
I'm able to boot normally if I blacklist the module in modprobe.d, but
due to other unrelated issues caused during troubleshooting, my graphics
drivers are not currently functional and I'm unable to confirm whether
or not audio is still functional without the module enabled.
