This bug also affects my laptop.The kernel of my Ubuntu 21.10 was

After updating the kernel to 5.13.0-23-generic, everything seems very
very slow. The operating system takes a long time to reach the desktop,
applications like google chrome, telegram take a long time to open. Till

grub menu while starting the computer, and select an earlier kernel
version, 5.13.0-22-generic in my case.

Seems like there is no device named wlan0. I think it is wlo1 instead of wlan0
on my laptop. When I replace wlan0 with wlo1, the results are as follows:
