Hello Peter,
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 3d30544f02120b884bba2a9466c87dba980e3be5 Author: Peter Zijlstra <peterz@infradead.org> Date: Tue Jun 21 14:27:50 2016 +0200
sched/fair: Apply more PELT fixes
The regression was introduced as of v4.8-rc1. The bug can be reproduced on an X1 Carbon with the following: stress -c $your_total_cpu_cores
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?
Thanks,
Joe
