Title:
Kernel Oops - unable to handle kernel paging request at
Status in linux package in Ubuntu:
New
Bug description:
I had numerous kernel panics after upgrading to the latest kernel.
Reverting to the previous Release 4.15.0-147 fixes the problem. I
first noticed this when my desktop was "stuck". I switched to the
console to run htop, to see if anything was blocking. And this seemed
to consistently trigger the oops.
