This bug also affects my laptop.The kernel of my Ubuntu 21.10 was updated to 5.13.0-23 just now. But on starting using this kernel, everything is very slow, and some things do not even open, like google chrome and telegram. My laptop has AMD ryzen 3500u processor.

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.
