 Could you get ddb(4) prompt by sending break via serial console
 at the point?
 
 After fdc(4), I guess mcclock at isa (which should be not matched) is
 checked, interrupts are enabled, and then fd0 at fdc0 is probed.
 ("scsibus0: waiting 2 seconds..." message should follow)
 
 If you can get ddb(4) prompt, I guess interrupts might be enabled
 but not served properly. We could get some info by backtrace anyway.
 If not, we should check where actually the hang occurs
 during cpu_configure(9), by sprinkling printf or so.
