Error message "ACPI PCC probe failed"

Does the system work OK otherwise?

You can safely ignore this message. It is just telling, that your computer's BIOS is not capable of a certain advanced feature (which currently is the case with almost all systems including mine). This message will show up with every boot, but is just informational and does not do any harm or indicate a problem.

Hi Manfred: happy new year to all! Maybe it's a good idea to add a new F.A.Q. for this recurring question?

It hangs up during boot but it starts and runs fine after I restart the
boot process...

Thanks. What does all of that mean?

Manfred Hampl suggests this article as an answer to your question:
FAQ #1163: “ACPI PCC probe failed”.

@Mark: Happy new year also to you.

I just created FAQ 1163
You are welcome to add your ideas.

@Arnett: I ask for your understanding that we are misusing your question to discuss a general approach to better cope with questions like yours.
I suggest that you just ignore that message.

That message is just informational and does not cause any boot hangs. If booting your system shows delays, then it has to be something else that happens _after_ the step that causes the display of that message.

Thanks

Oh. What could it be, I wonder?

If your boot process shows delays, then you should look in the system logs for big gaps in the time code.

You might try starting gnome-system-log, click on the cogwheel in the top right corner, select Open... and open the dmesg file.
The scroll down in that file and look for big gaps in the time code (e.g. jumping from 3.xxxxx to 11.xxxxx or something like that).
If you want us to check, please provide the three lines before that gap and the five lines after.

Thanks
