Title:
Ubuntu 20.04 freeze
Status in linux package in Ubuntu:
Incomplete
Bug description:
Ubuntu freeze short time after start. The system started freezing
after updating. I reinstalled 20.04.3 and it was still freezing. I've
installed a fedora 34 and the same thing happens. If I install 20.04.1
without updating then the system is working. When I boot into kernel
5.4 recovery, and boot to the desktop from there, it works. But when I
only select kernel 5.4 it also freezes.
