With fastforwarding off the system works well and boots without panicing.

As for the rtfree messages, they were caused by
net.link.ether.inet.proxyall=1 and were not connected to panicing.

Best regards,
Vladimir

Hi,

Can you try this with fastforwarding off?  It looks like a double free
somewhere in the ip_fastforward() routine.  Someone frees m but does
not NULL it out and at the drop: label the mbuf m is valid but the
data within it has already been freed.  Knowing if this is related
only to the fast forwarding case will help.

Best,
George
