I also have an Intel board (INTEL DQ35JO) and had posted last month
with a boot hang in the same place.   I recieved a quick reply from
the list and setting hw.pci.mcg=0 fixed everything.

Should this be marked as a known problem somewhere on the wiki?  It
appears to happen to Intel boards with onboard graphics and I imagine
that as more people migrate from 7.x to CURRENT that this will happen
to more users.

Thanks,
