The "choose a kernel" is the grub menu, and unless you've disabled it, you
can still do it. Try hitting any key as soon as you see the "about to boot
... in x sec"

I'd boot to single usermode (s at the end of the kernel line), and check
the logs.

And I really, *REALLY* don't like Supermicro. We've got a large bunch of
servers from Penguin, who's all Supermicro, and we've sent a ton back for
repair, as well as doing things here, *and* several of those sent back
were sent back more than once.

Luck.
