Hi, with the last git the warning disappear, thanks. Now I would like to submit a new issue : with the last git and with the 4.14.89 also, if I run latency-test without the kvm guest on, everything works fine. If I run latency-test with the kvm guest on the system hangs! The entire system not only the guest. This doesn't happen with the 4.9.146. Any hints to debug it? Thanks in advance
