[Bug 1939347] Re: Ubuntu 20.04 freeze since kernel 5.11

apport information

** Tags added: apport-collected focal

** Description changed:

Since the last kernel update 5.11.0-25-generic, the system freezes in a few seconds or minutes, sometimes even on the login screen.
The machine is a recent dell latitude 7490. The graphics card is Intel Corporation UHD Graphics 620 (rev 07). No multiboot. No problem with the previous kernel 5.8.0-63.
I had the same problem with fedora a few months ago, which forced me to switch to ubuntu without any problems so far.
Thanks for your help.
