Well, I am/was seeing what looks like the same panic but I don't have any sk(4) hardware (I have em(4) instead). Mine is: Slab at 0xc4d1efa8, freei 8 = 0. panic: Duplicate free of item 0xc4d1e800 from zone 0xc0c45080(mbuf_packet) I posted about it previously here: http://docs.freebsd.org/cgi/getmsg.cgi?fetch=60704+0+archive/2006/freebsd-current/20060917.freebsd-current Jos > It's currently running OK again on an kernel from Aug 19. dmesg from > this old kernel attached.
