Rings a bell and -- if not already fixed -- could be related to (rather
longish thread):
    http://mail-index.netbsd.org/port-xen/2009/10/30/msg005523.html

Synopsis is that bus_dma(9) usage in fxp could be a problem, or the
device itself (64-bit DMA).

Manuel also posted a patch, no idea if it helps:
