Hey Martin.
The issues reported on comment 1 and commment 24 have different stack
trace signatures, and do not seem to be the same issue at all.
I'll thus mark this bug as Invalid as apparently you couldn't reproduce
the original issue anymore.
If the new issue is still present with the latest 5.4 kernel in
-updates, please feel free to report a new bug.
Thank you!
