TobiSGD I should have listened to you from the beginning and posted to bugzilla. When I did post I got a reply from kernel developers Aaron Lu & Rafael J. Wysocki. They advise two changes in the kernel configuration in "current testing"
CONFIG_INTEL_MEI is not set
CONFIG_INTEL_MEI_ME is not set
After rebuilding the 3.10.2 kernel with the changed .config all is well
Thanks to all who offered advise
