Hi, I have discovered that it's possible with a very good repeatability (90% or more) to start the second core by pressing power button promptly during the 5 second period when BSP have sent startup IPIs already and is waiting for the AP going online. I am not sure how to interpret this info - perhaps there is some problem with caching BSPs LAPIC writes, and interrupt generated by the power button causes the cache to be flushed. Any ideas? -Maxim
