Kernel crashes when booting on LGA 1200 / G6405 without monitor connected

I've assembled a new machine with Intel G6405 / LGA 1200, motherboard Gigabyte, 8GB RAM, no discrete video card.

It boots fine with monitor connected, after I added nomodeset to /etc/default/grub:

GRUB_CMDLINE_LINUX_DEFAULT="nomodeset text"
GRUB_TERMINAL=console

But it still fails to boot without monitor.

journalctl -b1 for the failed boot: https://gist.github.com/warvariuc/8e3977b5115797276dcc0d9ed981d14f

My guess it's a bad driver for the newest CPU. Can anything be done to be able to boot without monitor?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
