Comment 21 for bug 1801743

Unfortunately, not for me. We have a bunch of (theoretically) identical computers in a new classroom, and on one of them this issue is present. Similarly as described by Carsten Gräser (graeser): last entry in kern.log, running fan and no reaction to either keyboard or power button, last message on screen being

A start job is running for Hold until boot process finishes up (21s / no limit).

Only the power button is blinking, not steady, and with addition of similar problems at the shutdown (NOT at the reboot, except for the long delay). It seems that the system thinks from certain gauges that it is suspended or powered down, but some part of it is not. Last message for the failed shutdown is

reboot: Power down

and then everything stays as if there would be the classic message "It's now safe to power off Your computer", with screen on and fan running.

To reinstate, installing the upstream kernel 4.19.1 did not help on this issue. Some 30 PCs of identical hardware do not have this problem.
