PS: On 5.08 kernel, the bug appears too, but in different form. Instead of "whole-kernel-freeze", some processes trying to write on btrfs filesystem hung, same as some system utilities. The hanged processes sometimes remainded in the system as zombie (as orphans under systemd init), without posibility to remove them (even using waitpid gdb).

There are then usually errors in "journalctl" (after some occurences, nothing is logged, but it is probably due to incompleteness of the writed logs). During each freeze more errors are logged and the error differ, so I append complete logged errors from two cases (I can post more "cases", if it will help). Both memcheck and smart says no error, and without the dock the notebook works fine.
