Title:
   kernel 5.13.0-23 extremely slow boot on AMD proc/graphics

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  5.13.0-23 HWE kernel on Linux Mint 20.2 Xfce (Ubuntu 20.04.3)
  Had been using the 5.13 HWE kernel for months with no problems.
  Today the kernel and linux-firmware updated.
  5.13.0-23 kernel now takes about 2 minutes to boot to the login screen.
  Normal boot time is 8 seconds.
  During that time the pc is frozen with only a _ underline cursor that doesn't 
flash.
  Can't change terminals with Ctrl+Alt+F1, etc.
  Problem does not occur when booting 5.11.0-44 or 5.4.0-92 so I'm pretty sure 
the problem is in the kernel and not linux-firmware.
