Title:
  Laptop won't properly shutdown after kernel update

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  After update from linux 5.13.0-21 to linux 5.13.0-22 my laptop won't
  shut down properly, instead it would almost shut down, but then get
  stuck in a state, there screen is black, but fans are still working,
  CPU generating heat and blue LED on a laptop case is on. Computer does
  not react to any key, only thing I could do is forcefully shut down by
  long pressing power button.

  Older kernel version still works as expected.

  I've noticed exactly the same problem with another OS on that laptop
  when updating from 5.11.0-40 to 5.11.0-41.

  Laptop is Acer A515-41G-T4MX. It has two AMD GPU's, one is buit-in,
  and another is "discrete". I use "legacy bios" mode instead of UEFI.
