Hi,

>Description:
        I have a Thinkcentre m910q that will only successfully upgrade itself
        with sysupgrade if I plug in a monitor.

        The problem appears to be that the upgrade kernel fails to boot and the
        system resets before the upgrade can take place.

        Looking at the dmesg buffer from the time the system is going down for
        reboot and the RAMDISK_CD kernel is booted, I see:

        And so you see, the last line of the upgrade kernel is truncated:

        pckbd0 at pckbc0 (kbd slo

    I also note weird corruption in the log, e.g.:

    acpipwrres at acpi0 not configuredigured

        Looking on the internet, a reddit post from 2 years ago describes the
        same problem from multiple users:

        https://www.reddit.com/r/openbsd/comments/n37du8/sysupgrade_didnothing/

        Talking amongst fellow porters on icb:

         - robert@ saw this on a hetzner dedicated machine
         - lraab@ saw this on a Thinkcentre m710q
         - tb@ reckons APUs do this too.

        (I don't know if this is related, but this system also fails to stay
        suspended. It will suspend, but wake up automatically a few seconds
        later. I don't know if the upgrade issue could be to do with a screwy
        ACPI implementation?)

        For now I've been working around this using the manual "untar it over
        the running system" method, as I need this box to be headless.

        Let me know if there's more info I can supply. Cheers.
