 almost certainly there is an entry-point/code-path into the networking 
 code from the rum driver that does not set the current vnet context.
 
 the easiest way to find this point is to compile in hte kernel 
 debugger, (options ddb and kdb) and then make it happen again.
 then get a stack packtrace (bt).
 this will show us exactly what the code path is.
 
 There is a small possibility it is a generic path from usb code 
 through usb-based netywork interfaces, as I remember something like 
 htis being fixed in -current but I don't remember exactly the details..
