Same problem on two identical machines that have dual 1Gb/s ethernet cards on the motherboard. This apparently causes booting to stall for about a minute, see this snippet from syslog after a boot. These timestamps are while the machine is booting, and hasn't gotten to the point where it presents a login prompt.
