 Encountered basically the same thing with yesterday's 9.99.17/amd64
 It may be the same computer. Backtrace looks slightly different now:
 
 panic: LOCKDEBUG: Mutex error: mutex_vector_enter,530: spin lock helod
 lockdebug_more
 mutex_enter
 uhub_intr
 usb_transfer_complete
 xhci_softintr
 xhci_poll

 wskbd_cngetc
 wsdisplay_getc
 cngetc.part.0
 cngetsn
 setroot  <- one issue is because of dhcp timeout, nfs root (wm0) couldn't be
             mounted
