I just installed ubuntu 22.04 LTS in my dell inspiron 5410 pc. There are 2 problems.
while i try to poweroff , it automatically restarts with “ACPI error. AE not found,while evaluating GPE method(L69)”. It runs some error logs and then poweroff after 2 minutes.
Always CPU uasge is high as 90% .
I used ‘top’ command to find which is taking high CPU uage ,
USER : root
COMMAND : KWORKER+
%CPU: 90(average)
