 Just confirmed the problem, errors happens at:
 
 Stopped in pid 0.5 (system) at netbsd:callout_softclock+0x5f:  movq
 %rcx,0(%rdx)
 
 The keyboard is not responsive at this moment, so can't get further
 backtrace at this moment. Problem doesn't happen with -current kernel.
 Maybe some missing USB pullup or some other partial pullup.
 
 Does the callout_softclock() ring a bell for anyone?
