ACPI BIOS ERROR (BUG): Could not resolve symbol [\_SB.PCIO.SATO.PRTO._GTF.DSSP] AE_NOT_FOUND (20190816/psargs-330)

My Ubuntu 18.04 system has been working fine for quite some time (a few years). It suddenly threw up this error. Causes the system to auto-reboot several time. Sometimes it is able to boot into the login but even after login, it is behaving in a cranky manner. What gives?

linux kernel 5.4.0-42-generic

Update:

1. The BIOS was updated and that resolved the crazy auto-reboot issue and made the system usable.

2. I found that this Error appears in the dmesg log of both 18.04 and 16.04. Below is a more detailed list of the ACPI error msg (I found some related ACPI msgs was issued but without the ACPI syntax). It seems the issue pertains to the method _GTF. What is that and what does it do? Also, what is a DSSP?

More details from dmesg on the error:

I found a detailed explanation of this problem here:

Long story short (code highlighting my own):

The proper fix is simply to boot your kernel with libata.noacpi=1and resume works again, YAY \o/

To make it permanent on Debian, edit /etc/default/grub and set the following line:

GRUB_CMDLINE_LINUX_DEFAULT="libata.noacpi=1"

Then regenerate grub config by running update-grub.
