[Sa Nov 30 06:25:03 2019] Fixing recursive fault but reboot is needed!
Can somebody interpret this error message and give me a hint where to search
further.
Or is this a known (and maybe fixed) error?
Sorry, but I cannot give the other information (as stated in the reporting
guidlines) on
the Ubuntu Rasperry Version, because they are not available...
Regards
Sven
