I've found trying to upgrade such a system with this bug to be very difficult.
It just hangs while attempting the upgrade (post the reboot). Attempting an upgrade via a usb install does much the same. Is slow to prompt to ask for keyboard layout. After that, just hangs. Perhaps me having setup a software raid1 made this bug worse.
