[ERROR ON BOOT] Error parsing PCC subspaces from PCCT

Hello everybody, sorry to bother you but I'm getting the following error
[0.460665] Error parsing PCC subspaces from PCCT.
I'm on a Thinkpad t440p.

I searched all over around but could not get something to get rid of that (Arch is starting, and everything is working but the error is still there).
Tried updating the BIOS to the latest version.
I have win7 installed in another partition but it was installed without EFI. Also, I selected LEGACY ONLY boot on bios.

Does anyone know what could be causing this?

Re: [ERROR ON BOOT] Error parsing PCC subspaces from PCCT

Seems to be a regression with the 4.10.x kernel, though I found results referring to older kernels too. I don't think any solution exists yet.

Re: [ERROR ON BOOT] Error parsing PCC subspaces from PCCT

Thank you, is there something to worry about? or just 'ignore' it till a newer kernel fix it?
I don't get what it's refering to, so don't know the severity either hmm

Got the same error. No news on bugzilla. Do we have any news here?

Re: [ERROR ON BOOT] Error parsing PCC subspaces from PCCT

@LnX_Archer welcome to the arch linux forums.  linux-hardend is now on 4.13 so you could try to see if the bug has been fixed in that series.
If not I suggest you check if the bug report has been filed upstream at https://bugzilla.kernel.org/.

Re: [ERROR ON BOOT] Error parsing PCC subspaces from PCCT

The `linux-lts` doesn't have this problem, as this is kernel 4.9. Tested on Thinkpad x250. Every other kernel 4.12/4.13 (such as `zen` and similars) show the warning errors

Re: [ERROR ON BOOT] Error parsing PCC subspaces from PCCT

The bug report states this bug was recently fixed in kernel 4.16.12. I still get the error message. Are you guys still getting it?

Re: [ERROR ON BOOT] Error parsing PCC subspaces from PCCT

No, it states it's fixed in "kernel-4.16.12-300.fc28" and "kernel-4.16.12-200.fc27" because fedora included pending pataches, see https://bugzilla.redhat.com/show_bug.cgi?id=1435837#c82
So… are you running fedora?

From the redhat bug report it was fixed in kernel-4.16.12-300.fc28 kernel-4.16.12-200.fc27 are you running one of those specific kernels?
https://git.kernel.org/pub/scm/linux/ke … 34b0e7e615 only changes comments
https://www.spinics.net/lists/linux-acpi/msg82033.html not yet applied to mainline
https://git.kernel.org/pub/scm/linux/ke … b0e402283c this should be the needed patch
Edit:
Does apply cleanly to 4.17 if you try building 4.17.1 with the patch applied and it resolves the issue for then you could open an issue on the arch bug tracker asking for the patch to be applied.

Re: [ERROR ON BOOT] Error parsing PCC subspaces from PCCT

The patch worked for me with Linux 4.17.1.  I followed the kernels/traditional wiki method. Thanks again for all the hints. I opened a bug report for it as well.
