>Description:
    When attempting to use a network card which uses the vr drivers (see vr(4)), after the card is attempted to be initialised (during boot) there is a continuous stream of error messages (once every 30 seconds or so):

vr0: watchdog timeout.

The network card is unusable (ie. cannot connect out and nothing can connect in).
>How-To-Repeat:
    Install a network card which attempts to use the vr driver.
>Fix:
      A workaround which is reported to have worked is by disabling apic -
