Upgrade 2.3.3 to 2.3.4 = Boot Failure
Updated via the GUI, and received my notification that all should have been well: "Upgrade is complete. Rebooting in 10 seconds."
Went back to the browser tab and see that it continually is counting down from 20 and restarting the countdown, since it referred to the system as not yet ready.
Eventually hooking up keyboard and monitor, I see that it fails to boot, but have zip for background with FreeBSD and how to get anywhere past what you see in the attached photos of the screen.
What hardware are you using? It all works fine here, virtual, hardware, upgrade, clean install, all works with no problems. Even a CF card still works.
