GEOM: ada0: the secondary GPT header is not in the last LBA or random: unblocking device. when using more than 2 cores

[Nicolas Embriz]

Hi, I notice that in 11.1 there is this new option EARLY_AP_STARTUP, I add
it to the kernel and testing also with a GENERIC and seems to be working
(no panics when using more than 2 cores)

But wondering what exactly “EARLY_AP_STARTUP” does and why is that when
using one single core kernel and not using this option the kernel doesn't
panic but if using more than 2 cores it panics at boot time.

Regards.
