getty repeating too quickly on port /dev/ttyv0

[Matthew Dillon]

    It looks like the USB driver is having trouble with the keyboard,
    possibly an indication that the USB interrupt is not working.

    Try plugging the USB keyboard into a different USB port.

    If that doesn't help, then emergency interrupt polling can be enabled
    and you can try bumping the frequency up as a workaround.

    sysctl kern.emergency_intr_enable=1
    sysctl kern.emergency_intr_freq=50
