I use Cockpit to manage my RL9 server remotely. When there are kernel updates I reboot the system via the Cockpit interface. Each time I’ve done this, at least twice, the process stops till I go and turn on the monitor attached to the server.
So I did another test just now logging in via ssh and rebooting and the same thing happened, it stalled, but I added a subtle difference described as follows.
My server is connected to a monitor via a KVM switch, which in this case is enabled for another machine at the time of reboot. With the monitor off, to continue the reboot all I had to do was switch the KVM to the rocky machine.
How do I prevent this from happening?
This did not happen when I was running RL8 with same setup.
There is a difference, I upgraded the KVM switch from VGA based to HDMI based since my other machines don’t have VGA connections, done soon after installing RL9.
There are two parts to a reboot, Shutting down and then efi firmware boot process.
Is the HDMI interface causing the machine not to shutdown completely, I can check logs for that or is the firmware hanging on boot?

The only thing I see is the watchdog timer not shutting down. It says it has a 10 min. wait.
