Had the problem where the Supermicro IPMI keyboard wouldn't work on some machines for a while, tonight I finally had time to play with all the options to see if anything would make it work. Turns out adding the following to loader.conf does fixes the issue: hint.ehci.0.disabled="1" So the question is why would this help? Surely disabling one controller shouldn't make devices attached to another work?
