This is a post on behalf of a friend.

Is there anyone out there running an SMP kernel, 3.0.1, and using PF as 
an LKM (in order to use ALTQ, apparently)? We've got the machine booting 
an SMP kernel just fine, but after installing the new LKM modules (cd 
/usr/src/sys/lkm; make install) and trying to load the pf.o module we're 
getting:

LKM 'pf': environment compile options mismatch - LKM '', kernel 
'MULTIPROCESSOR'

Any ideas what we might be doing wrong here?

Thanks in advance,
