I just upgraded to:
FreeBSD jclarke-pc.cisco.com 9.0-CURRENT FreeBSD 9.0-CURRENT #6: Mon Oct
12 14:23:45 EDT 2009
marcus@jclarke-pc.cisco.com:/usr/obj/usr/src/sys/JCLARKE-PC i386
A few minutes after a reboot, I see:
panic: sbsndptr: sockbuf 0xc5ba7c2c and mbuf 0xc5471300 clashing
#3 0xc0667c1a in sbsndptr (sb=0xc5ba7c2c, off=Variable "off" is not
available.

This machine uses em, gif, and PPP (tun) interfaces (with IPv4 and v6
addresses). I have since rebooted, so it may not be possible to provide
many more details from this crash. However, if I see the crash again,
is there anything more I should provide?
