Maybe your reboots are related to a problem I had with several Dell  
1750's and 2850's.

I added:
> [rutger@darwin rutger]$ cat /boot/loader.conf
> debug.mpsafenet=0

to some of the affected systems and they have not crashed yet in  
about 8 days. Your dump seems to indicate a failure somewhere in  
netinet code, maybe it's locking related as well...

Met vriendelijke groet / Kind Regards,
