With 14922 installed, during startup I see the same output repeated during machine boot, and overall I still have a much slower boot with PD7 installed. It actually loads the hypervisor, unloads it then reloads it again! Shutdown is still slower too with log entries there disabling cacheing still. Will upgrade to 14924 but it doesn't mention fixes to bootup speed.
