On Mac mini Mid 2010 (Macmini4,1) (which contains the NetXtreme BCM57765 Gigabit Ethernet PCIe) helloSystem 0.7.0 becomes unresponsive then the Ethernet cable is plugged in. If the Logs utility is open, the last message seen in /var/log/messages is bge0: watchdog timeout --resetting. Even with dev.bge.0.msi=0 and/or hw.bge.allow_asf=0 in /boot/loader.conf, the system becomes unresponsive as soon as the Ethernet cable is plugged in.
