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.
