I am testing with smp enabled. And I added those messages (and more) to the kernel's handling of boot -v . My boot attempts are a mix of failures and successes, sometimes dozens of failures in a row. Sometimes multiple successes in a row. > Booting with usefdt=1 and debug.verbose_sysinit=1 I was testing a usefdt=1 type of context but not a debug.verbose_sysinit=1 type of context.

Then I see : > vt_upgrade(&vt_consdev)... As I remember I've got sc (syscons) set up by default, not vt. My environment has both built (via a Nathan W. suggestion).

I've not tried vt in a while, if I remember my defaults correctly.
