Public bug reported:
I've updated from 21.04 to 21.10 and that bug has appeared in kernel
5.13.0-19. When 2 displays are connected simulateneously (DP and HDMI)
before graphics server is started the kernel hangs up and reports that
cpu is locked up. Boot with 5.11 kernel doesn't produce that problem.
PC is based on i7-11700 CPU.
Here is part of kernel log with call trace:
