>Description:
My FreeBSD box comes with Tyan S2892 with SMDC M3291 for IPMI. The onboard NIC is broadcom BCM5704.

The IPMI can't work after bge driver loaded. I searched all possible and patches for bge and failed. In my case, if I enable hw.bge.allow_asf->1 and the system reboot unexpectedly when system try to communicate to bge (for example, invoke DHCP to assign a new IP). 
>How-To-Repeat:
Set hw.bge.allow_asf=1 in /boot/loader.conf and reboot.
>Fix:
