Hi! (Hope this is the right place to ask this)
I have a BCM57781 adapter built into a new ASRock motherboard. The
adapter runs great, however it periodically dies - about once a day.
When it dies existing connections (like ssh) work fine, but any new
incoming or outgoing connections fail. I am not running a firewall. When
in the crashed state I've checked my ifconfig/routes/resolve.conf all
looks good. I have also checked the max/current sockets in sysctl and it
is nowhere near the max. The only thing I can do to get my connection
working again is /etc/rc.d/netif restart.

What can i do to troubleshoot this? I've checked the bge manpage and
don't see anything related to debugging.
