Ubuntu for Orange Pi 3 LTS - hanging on shutdown

tap1956

When shutting down, the line system-shutdown: "Waiting for process: cpu, grep" appears first. After about a minute, the same line appears, the cursor is under it and the computer freezes. I have to turn off the power to shut down. Moreover, this effect also occurs when I log into the system (automatic login), do not run any programs and then select Shut Down from the menu. How to fix this error? I attached a photo of the screen.

I don't know how to fix it as such, but it's caused by lscpu hanging. (The grep is likely just a grep on it's outputs).

I've had this issue on the zero 2. It stopped the resize sdcard on first boot script. In that case  I edited the script to skip the lscpu command as I new the answer lscpu was going to retrieve on my specific system.

Thanks for the reply. I switched to Debian, there were no such problems there. Turns off almost instantly. And the differences in the interface are insignificant.

In my opinion, the repeated “Waiting for process: cpu, grep” message could indicate that a background process or service is hanging during shutdown. I would probably start by checking system logs and recently installed drivers or updates, because those problems often cause shutdown conflicts. Troubleshooting issues like this reminds me of Slope Rider, where I need patience and careful adjustments to get past difficult sections without crashing. I hope the attached screen photo helps identify the exact process causing the freeze, because I know having to force the power off repeatedly is not good for the system in the long term.
