Just to Chime in:
Brand spanking new 16" Macbook,
Big Sur 11.5.1
Lenovo dock ldc-g2 connected over USB-C, monitor on DisplayPort
Multiple hard crashes a day with this same kernel panic error, mostly when removing or reconnecting the dock, maybe 5-10s after it.
I am going to swap this out for an HDMI cable this weekend and report back on results.
