Lack of entropy ? I started using haveged on some _desktops_ to
speed up the boot, but I think that with changes in linux-5.3 that
is probably no longer necessary.

I thought my boxes were running ok after rebooting my cheap network
switches (and apart from problems with my consumer-grade KVM which
is just a pain when the monitor has been switched off: in theory,
turn on monitor, change active position to a machine which is
either running or will wake/boot when panel switch is pressed -
sometimes ok, sometimes not).
But this afternoon I left my completed test server build running so
that its cron backups would run - timeout because nfs target directory
still mounted. And now the same on that desktop box. <sigh/>
All I can add is that although 5.3.11 seemed to be ok I later got
the same problems with that.
