I applied attached patch against 5.3-STABLE as of 6th Jan., rebuilt kernel and restarted, top shows correct CPU usage. vmstat too. While machine is as a server, suspend / resume is not tested. The machine is; two Pentium III on Tyan S2567U3AN Thunder HEsl with ACPI turned off. One amr and one em, both on 64bit 66MHz PCI bus, and one ATI RAGE XL on AGP. -- UEMURA (fka.
