Public bug reported:
Hello,
When performing a clean install of ubuntu 20.04.3 LTS on my laptop, I started
have problems booting very often. The screen presented the text message:
soft lockup - CPU#x stuck for 22s!
If i install ubuntu 20.04.2 LTS and proceed with every update (including
the kernel update included in normal updates), I am not being presented
with this problem. As of right now, this is the configuration presented
in my laptop:
$ lsb_release -rd
