I have a basic Dell Optiplex 7040 SFF PC, which comes with an i5 6500 and integrated graphics. There is only one SSD for storage and my configuration during installation was very basic.
After logging in, I did a “dnf update” and rebooted. Now whenever I try to reboot or shutdown the machine: “shutdown -r now” or “shutdown -h now”, the screen will turn off, the CPU fan keeps spinning, and the system hangs, never rebooting or shutting down.
I have installed no new software and this is the default configuration for Fedora Server at the command line. There is very little to go wrong. How do I debug this?
The kernel is version 6.5.7. If I choose the alternate kernel version 6.2.9 from the startup menu, I do not have this issue.
The only solution is a hard reset from the button on the front panel, which is less than ideal for a headless server that’s to live in a closet.
