Hi Vikas, A kernel bug report was opened against Ubuntu [0]. After a kernel bisect, it was found that reverting the following commit resolved this bug:
commit 24247aeeabe99eab13b798ccccc2dec066dd6f07 Author: Vikas Shivappa <[email protected]> Date: Tue Aug 15 18:00:43 2017 -0700 x86/intel_rdt/cqm: Improve limbo list processing The regression was introduced as of v4.14-r1 and still exists with current mainline. The trace with v4.15-rc7 is in comment #44[1]. I was hoping to get your feedback, since you are the patch author. Do you think gathering any additional data will help diagnose this issue, or would it be best to submit a revert request?
