 fxp0: <Intel 82801CAM (ICH3) Pro/100 VE Ethernet> port 0x4000-0x403f 
 mem 0xe8200000-0xe8200fff irq 9 at device 8.0 on pci2

 Had problems building anything on the system, it does not stay
 running long enough to do anything, like even getting /bin/sh
 running.
 
 > - Does this still happen with 5.3-BETA?
 
 Again not sure, since I have not had time to try the newer versions.
