I'd power off fully then back on. There's no reason that a USB device should hang up boot - worst case it simply isn't initialized properly. Also remember that the first boot after a firmware flash will take a good bit longer.
There's nothing I can do in firmware to fix Ubuntu's installer putting the bootloader on the wrong drive. The regular desktop installer doesn't have this issue, so I'd say it's a bug with the server installer.
And as always, if it's not broken, don't fix it. There's no need to update the firmware with each release unless you're experiencing an issue that's explicitly listed as being fixed in the changelog.
