There is one additional "error" message after the message "Waiting for /Dev to be fully polpulated...": "Driver 'pcspkr' is already registered, aborting..". ;-) Unable to locate IOAPIC for GSI 2 and 9 is reported as the first messages from dom0 kernel, but those messages are also present when booting w/o TXT = Enabled setting. When I remove the 'quiet' kernel parameter, the mast messages seen are sometimes from DRM and from USB otherwise.
