I have an Acer Aspire One and have noticed a very long delay in boot up because of "intel cpu microcode update" so I removed the microcode package and boot times are much faster now. Hopefully the removal doesn't cause a problem. The AAO has Intel Atom cpu so don't know if the microcode update even pertains to it? Any Ideas?
EDIT: went to Intel site and see that it is valid to use for Intel Atom but why the long delay is puzzling maybe something to do with debugging so I better reinstall or maybe just wait to see if it breaks.
