--- Comment #13 from Yury Puchalski (pooh at aikipooh.name) ---
I think it's the right place to discuss:)
Using gentoo, kernel 6.6.38, and 5.15.41 had it the same.

It's Dell Precision M4800, integrated intel card, and additional nvidia. I'm
using nouveau driver, nvidia setup as primaryGPU for X.

The usual line is there.
[    4.295646] ACPI Warning: \_SB.PCI0.PEG0.PEGP._DSM: Argument #4 type
mismatch - Found [Buffer], ACPI requires [Package] (20230628/nsarguments-61)

But then, what's very bad, I get temporary freezes regularly. Sometimes it's
every 10-15 seconds, sometimes it doesn't happen for prolonged time.

Every such message is followed by:

These freezes result in music hiccups, mouse pointer not moving for 2-3
seconds. What can I do to sweep them under the carpet? acpi=off?
