This sytem has started locking up on poweroff or restart but not everytime. I have looked into the logs and can't find anything there. It does it from the desktop restart/shutdown as well as a terminal poweroff. I've waited a few minutes thinking something is unloading but no luck. I would like to next run a verbose grub setup hoping something might turn up there. My question is can I safely edit out the "quiet splash $vt_handoff" permanently in the grub options and saving or should I manually edit at each startup and not save the change? Any hints would be appreciated.
