Performance decline. No trace found.
by sunmoon from LinuxQuestions.org on (#4Z8XQ)
I started to experience the performance decline on my laptop. Usually it appears on the cold morning boot, but can occur after a few hours of work too. The system doesn't hang, the mouse moves, but even to launch the console with a shortcut key takes a couple of minutes.
The only difference I found so far is the presence of records `perf: interrupt took too long` in `dmesg` (see the attachment). Can't figure out how to trace the origin of the problem.
