That would indicate that the rc script applied an > update, which would imply that the boot-time update failed somehow. when i ran the rc script after boot i saw the CPU related messages in dmesg on the console (CPU count, type, features, etc). i did not see anything in /var/log/messages of interest either. i'll re-test tomorrow when i get back into the office and let you know if i see anything of interest. my plan is to: - boot with the /boot/loader.conf additions for applying microcode and save the output from x86info - boot with loader.conf settings uncommented, view output of x86conf - then run rc script and get output of x86conf -pete -- Pete Wright pete_at_nomadlogic.org 310.309.9298Received on Tue Sep 11 2018 - 01:55:29 UTC
