What hardware are you running on @1mehal ?

@bflanagin
It's
i9 - 12900
GeForce RTX3080
Samsung 980GB NVMe M.2
Seagate 2TB
ASUS Z690-PLUS WIFI D4

Looks like issue is related to the kernel update.
I've tried following:

1. Installed "20.04" version of Pop!_OS, system reboot and shutdown worked just fine for me. But I have upgraded to kernel 5.15 and it stopped working.
2. Installed "20.10" version of Ubuntu - reboot and shutdown hangs
3. Tried to install GRUB for dual-boot, tried to play with grub loading parameters (enabling EFI boot, forcing ACPI, etc). No success there.

I would appreciate any advise

Hello guys!
Just installed kernel 5.13.19 and reboot works just fine. But my WiFi adapter doesn't work with that kernel

With kernel 5.14.21 - everything seems to be working good.
