 Looking back through the 'dmesg' output with the eap(4) enabled reveals
 that skc0, eap0, ehci0, and the onboard uhci0 all share the same interrupt
 line (9):
 
 [...]

 Perhaps that is significant in the failure to find the root device?
 (It definitely is in the eap(4) panic case, but that's out of scope.)
