Running Ubuntu 22.04, Kernel 5.15.0-40-generic x86_64 Since the last kernel update about 3 weeks ago, I have started to get the following errors:-

I have updated the ASUS laptop with the latest BIOS version V322 - but this has done nothing.

ACPI errors shown here...

This is a known bug in certain versions of the Linux kernel (5.12.x and 5.17.2+, among others) with Collaborative Processor Performance Control (CPPC) affecting Intel CPUs. The kernel guys are working on a patch:

To get rid of these messages while booting, you can add loglevel=3 to GRUB_CMDLINE_LINUX_DEFAULT in etc/default/grub, so that it will look like this:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash loglevel=3"

then update grub using command: sudo update-grub

Note that, adding 'loglevel=3' simply disables the non-critical error but doesn't resolve it. Since this is an active issue reported on bugzilla and has been resolved for 5.18.xx kernels, you can try upgrading your linux kernel to this version using software and updates. Hopefully, it could be resolved soon for 5.15.XX and other kernels. To get more info on why this happens @LordBoltar has explained very well in this thread.

in my case I had similar error

 ACPI Error: AE_NOT_FOUND, while evaluating GPE method [_L09] (20220331/evgpe-511)
 ACPI BIOS Error (bug): Could not resolve symbol [\_GPE._L09.D1F0], AE_NOT_FOUND (20220331/psargs-330)

No Local Variables are initialized for Method [_L09]
No Arguments are initialized for method [_L09]

and for me this was the solution

echo "mask" > /sys/firmware/acpi/interrupts/gpe09

but after reboot you need to rerun this command again

It was solved to me after typing update-manager –d on the terminal.

Hope it can be useful to you.
