Machine locks on restore from hibernation after upgrade to  kernel-default
5.14.21-150500.55.83-default, three days on a row.

Machine hibernates normally, but on restore, keyboard leds freeze, does not
respond. Display shows the frozen screen saver animation. Machine appears
frozen. There is nothing saved on the log after the apparently successful
hibernation.

I am removing this kernel and going back to 5.14.21-150500.55.73-default, but I
still have the journal if you are interested.
