Description aryeh.friedman 2020-11-29 20:43:46 UTC

If you hit ctrl-alt-delete during the device probe phase of booting the machine freezes (no panic, further output or any other further progress in the boot process).  Machine does not respond to any input.   Only way to fix the freeze is to power cycle and then the machine boots normally afterwards.
