Re: Reboot loop

There is
> com0 at isa0 port 0x3f8/8 irq 4: ns16550a, 16 byte fifo
in your dmesg.

So, I assume your box reports com port somehow (via ACPI probably)
Some boxes may have comport built into chipset but no external cable for it.
I have one, I bought cable separately.

Another option is to use UART that connects to USB
