Greetings,
Kernel bound workloads seem to trigger the below for whatever reason. I only see this when beating up NFS. There was a kworker wakeup latency issue, but with a bandaid applied to fix that up, I can still trigger this.
Hi,
i have seen this one as well with my system, but i could not find an easy way to trigger it for bisecting purpose. If you can trigger it conveniently, a bisect would be nice!
Workload permitting. To reproduce, mount your box NFS, cd to somewhere the NFS mount, and just do bonnie -s <memory size>. There, maybe you'll beat me to it. I hope so, I have multiple kernels doing the annoying "baby birds in a nest" thing at me literally endlessly :)
