Describe the results you received:
2 Warnings that should not be there(?)
Describe the results you expected:
No warnings
Additional information you deem important (e.g. issue happens only occasionally):
I've looked through Google and the issue tracker and cannot find a solution. I refuse to believe the 5.4.0-58-generic kernel is not capable of what the warning say. What did I miss?
