[Bug 1528684] Re: Error parsing PCC subspaces from PCCT

[Brad Figg]

This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
bionic' to 'verification-done-bionic'. If the problem still exists,
change the tag 'verification-needed-bionic' to 'verification-failed-
bionic'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

[Bug 1528684] Re: Error parsing PCC subspaces from PCCT

[dann frazier]

** Description changed:

  [Impact]
  A scary-looking message appears in dmesg in several places during boot:
  
  "Error parsing PCC subspaces from PCCT"
+ 
+ This could cause users to believe they have buggy firmware, in cases
+ where it's actually fine.
  
  [Test Case]
  dmesg | grep "Error parsing PCC subspaces"
  
  [Fix]
  Resolved in upstream commit that cleanly cherry-picks back to bionic:
  8f8027c5f935 mailbox: PCC: erroneous error message when parsing ACPI PCCT
  
  [Regression Risk]
  PCC is a generic ACPI-defined mechanism for the OS and firmware to 
communicate. Since the fix does change how the tables are parsed, regression 
scenarios could include breakages in PCC clients (things that use this layer to 
communicate to firmware). The only Kconfig option I see in bionic's source that 
depends on CONFIG_PCC is the CPPC library, which provides ACPI CPU performance 
management used by the cppc-cpufreq driver and is used by the scaling 
driver/governor for Sandy bridge processors.
  
  Tested on an Nvidia DGX system. This is an upstream fix, so any
  regressions will have upstream support.

+ A scary-looking message appears in dmesg in several places during boot:
  
- "Error parsing PCC subspaces from PCCT" (Portable C Compiler)

+ [Regression Risk]
+ PCC is a generic ACPI-defined mechanism for the OS and firmware to 
communicate. Since the fix does change how the tables are parsed, regression 
scenarios could include breakages in PCC clients (things that use this layer to 
communicate to firmware). The only Kconfig option I see in bionic's source that 
depends on CONFIG_PCC is the CPPC library, which provides ACPI CPU performance 
management used by the cppc-cpufreq driver and is used by the scaling 
driver/governor for Sandy bridge processors.
+ 
+ Tested on an Nvidia DGX system. This is an upstream fix, so any
+ regressions will have upstream support.

[Bug 1528684] Re: Error parsing PCC subspaces from PCCT

[PrPom.cz]

Same problem on Thinkpad L440, cannot even run Ubuntu, it crashes with this 
message on screen. Totally lost, have no clue, this discussion does not give a 
clear guide, what to do. 
Problem appeared all of a sudden, no new install, no dual boot.
Please help!!!

[Bug 1528684] Re: Error parsing PCC subspaces from PCCT

[schwobi]

Update:

The system crashes I mentioned are likely unrelated; I noticed a 3rd party 
daemon to randomly hog up all of my CPU.
... Nevermind.

##

Interestingly tough, I observed the 'Error parsing PCC subspaces from
PCCT' also while booting and running from a live-USB on the same system
as mentioned above (with all other /dev/sdX drives unmounted since I
intended to run a fsck check).

Just speculation from a Linux-beginner on my side, but doesn't this
indicate an issue with the motherboard firmware; i.e. conflicts in
either the BIOS/UEFI, MBR, etc.?

Ok, I've set up the internet connection and upgraded system with apt-
get. There's only problem with linux-generic, linux-headers-generic,
linux-image-generic. I don't know how to update it. There's still a
problem with generating a log with ubuntu-bug-linux.. I really
appreciate your engagement. Thank you

Unfortunately I cannot do this, I tried to generate this report file
also on older kernels I still have, but there's the same problem... I
just can't use "ubuntu-bug linux" is there any other way?

[Bug 1528684] Re: Error parsing PCC subspaces from PCCT

[Piotr Miszczak]

Hi, I still have a problem. When I write "ubuntu-bug linux" it shows that 
there's problem with linux-image-4.2.0-25-generic and it cannot report the 
error; that it's  not an official Ubuntu package (kernel?!) and ask to 
delete/uninstall all such packages. 
I also cannot update through apt-get... :( Temporary errors during translating 
repos... I'm not sure if my spelling is correct, I haven't got it written in 
english.
Please help, thanks a lot! It would be nice just to have an opportunity to 
update the system..

[Bug 1528684] Re: Error parsing PCC subspaces from PCCT

[Piotr Miszczak]

Thanks for response. It doesn't want to work due to unsupported packeges
(chrome maybe I don't know what else) but I dont have simple access to
my packages library or sth. Is there any simple way to uninstall all
unsupported software and clean repo? Thanks

Piotr Miszczak, it will help immensely if you filed a new report with the 
Ubuntu repository kernel (not mainline/upstream) via a terminal:
ubuntu-bug linux

Please feel free to subscribe me to it.

For more on why this is helpful, please see
https://wiki.ubuntu.com/ReportingBugs.

Thanks Christopher. Unfortunately your link to Lenovo has no BIOS files
to download for Ubuntu environments.

What's the most easiest way to upgrade BIOS on my machine then?

[Bug 1528684] Re: Error parsing PCC subspaces from PCCT

[Christopher M. Penalver]

Michael Heuberger, thank you for reporting this and helping make Ubuntu
better.

As per http://support.lenovo.com/us/en/products/Laptops-and-
netbooks/ThinkPad-X-Series-laptops/ThinkPad-X1-Carbon-Type-20A7-20A8? an
update to your computer's buggy and outdated BIOS is available (1.23).
If you update to this following
https://help.ubuntu.com/community/BIOSUpdate does it change anything?

For more on BIOS updates and linux, please see
https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette
.

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful. As well, you don't
have to create a new bug report.

Once the BIOS is updated, if the problem is still reproducible:
1) Please provide the output of the following terminal command (not perform an 
apport-collect):
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
2) Please make a comment specifically advising on if there was an improvement 
or not.
3) Please mark this report Status Confirmed. If it's not reproducible, please 
mark this as Invalid.

Thank you for your understanding.

** Description changed:

  On my Thinkpad laptop I am seeing this error every time after the boot
  in the dmesg output:
  
- "Error parsing PCC subspaces from PCCT"
+ "Error parsing PCC subspaces from PCCT" (Portable C Compiler)
  
  The attached log files should reveal more. I have no idea what it means
  but seems serious. Hope you can solve this for once and all?
