The old Dell pc I got given has a flaw. Every 3rd or 4th shutdown fails to do so. Even alt+sysrq+REISUB fails to work. I have to do a hard shutdown.
The next bootup usually fails. It takes longer than normal to boot and fails to allow access to the keyboard and mouse. I have to pull out the power cable and wait for 30 seconds. Any idea why?
