I encountered this originally on my main server:

This is an Intel DG45FC board.

The same kernel from May 21 also crashes in a VMware instance.  Using  
the same kernel config to create a kernel on the VMware instance also  
panics.  GENERIC from the same sources does not crash in a VMware  
instance; I haven't tried on real hardware yet.  Configs and the  
kernels are at http://www.lassitu.de/freebsd/ifconfig-panic/

I'm currently trying to take out things from the DIESEL config until  
it stops panicking or I end up with stock GENERIC, using my VMware  
instance.
