Verified this on a fully-enabled POWER8 system; confirming that without the patch, multiple CPUs show incorrect node values (random garbage): 144,18,3,0,,18,18,18,18 145,18,3,0,,18,18,18,18 146,18,3,436483456,,18,18,18,18 147,18,3,256,,18,18,18,18 148,18,3,436482464,,18,18,18,18

Steve, what exactly did you test? This issue looks a lot like what should have been fixed by 2.20.1-5.1ubuntu20.4; discontinuous NUMA nodes, but it's already the version that would have been used. I have access to a system which appears to show the issue, so I'll see if I can find which other

[Touch-packages] [Bug 1427995] Re: lscpu -p is showing wrong values for Node component

I've just done a test here with both Ubuntu 14.04 and Ubuntu 15.04 versions of util-linux (2.20.1-5.1ubuntu20.4 vs. 2.25.2-4ubuntu2), and I can confirm that the older version of lscpu gives different output on the same kernel. So yes, this is a bug in util-linux's parsing of /sys. ** Changed in:

Thanks for this additional information. This still doesn't answer the question of whether the bug is in lscpu, or in the kernel's /sys interfaces. Have you checked whether old util-linux with new kernel, or new util-linux with old kernel, works? -- You received this bug notification because
