Suddenly I can't reboot my computer
by hazel from LinuxQuestions.org on (#55ZD7)
It's not a disaster because I seldom want to reboot. My normal usage pattern these days is to switch on Slackware in the morning and switch it off around 18.00 hours. But sometimes I want to switch systems and that means rebooting.
The initial stages of the reboot (those that are controlled by the kernel) work normally. X shuts down, I see closing messages from syslog, and then the screen goes black. I assume this means that video memory has been cleared. But then things just stop. The darned UEFI must have been given some kind of "Reboot!" instruction but doesn't obey as it used to do.
If I briefly switch off at the main and on again, then of course it reboots. But that is really a cold boot complete with POST.
It's old hardware, bought second-hand as I buy all my stuff. But I'm curious all the same to know what is supposed to happen next during a reboot and why it's not happening. Is there anything I could do to find out?
PS: Good thing I'm not running Windows! You have to reboot that every time something updates.
