as far as I can see, state is back to normal with this kernel.
No more error messages or crashing modules and all devices seem to work
as expected.
Only thing is, that the external devices connected to the Thunderbolt
dock are coming up a little bit slower than with 5.0.7 - but this is
nothing, I'd worry about.

Thank *you*.
