Title:
Linux 5.11.0-25 & 5.11.0-27 panic when boot with thunderbolt dock
connected
Status in linux package in Ubuntu:
Confirmed
Bug description:
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).
