*** This bug is a duplicate of bug 2018504 *** https://bugs.launchpad.net/bugs/2018504 The problem is critical to servers or systems that have peak usage at times that consumes high CPUs. The motherboard's Ethernet port is connect to a 1 gbp/s switch. The wifi is used as a hot spot. on a AMD Ryzen 5 3600 computer, I observe the same.
