This bug is missing log files that will aid in diagnosing the problem. From a terminal window please run:

apport-collect 1338924

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

[Joseph Salisbury (jsalisbury)]

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.16 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

1.I can’t type “apport-collect 1338919” successfully, it will display a message like below link.
https://bugs.launchpad.net/ubuntu/+source/apport/+bug/1277794
2.Update the kernel to 3.16, “NUMA: Warning: node ids are out of bound” wouldn’t log in dmesg, but “WARNING: CPU: 9 PID: 0” & “warn_slowpath_common” & “warn_slowpath_fmt” still exist.
Please refer to the attached file:NUMA_warning_3.16.png

[Samantha Jian-Pielak (samantha-jian)]

Hi Aaron,

Can you install python-apport, and run "apport-collect 1338919" command again on 3.16 kernel system?
$ sudo apt-get install python-apport
$ apport-collect 1338919

[Samantha Jian-Pielak (samantha-jian)]

Wrong bug number. I meant to say 1338924.

[AaronLan (aaron-lan)]

Hi, Samantha

This issue was copy to Quanta project :1346412
Your last commend was as below:
"warn_slowpath_common" & "warn_slowpath_fmt" are part of the call trace for ""WARNING: CPU: 5 PID: 0", so Intel should be able to provide an explanation on these two.

I think this issue should be closed. Because we already transfer this issue to intel.
