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=3D1 and debug.verbose_sysinit=3D1=20 I was testing a usefdt=3D1 type of context but not a = debug.verbose_sysinit=3D1 type of context.

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