Public bug reported:

Hello,

My laptop run well with last 5.4 linux kernel even if I connect my
thunderbolt dock.

When trying to boot with 5.11.0-25 or 5.11.0-27 (hwe) kernel with dock
and 2 monitors connected, the kernel panic after 3 or 4 seconds. Without
the dock, he work fine.

After a lot of try, I was able to boot sometime on 5.11 with the dock,
but randomly and only if I only connect 1 extra monitor (I usually use
two).
