 Well, I've set the tunable as suggested, configured KPPP and am using it now. 
 So far, no problem, but I haven't been online for long either, so time will 
 tell if thats the problem. I came across this which states that if you are 
 using pppd, then you need to set the tunable to 0, if I read it correctly.

 This all makes me wonder, what is the advantage to having the debug.mpsafenet 
 set to 1 as default, anyway, if the computer only has a single processor? 
 Shouldn't the installer be smart enough to detect if the computer is single 
 or multiprocessor, and set the tunable accordingly, at least until ALL of the 
 network features are made MPSAFE so that it is no longer an issue? And, when 
 installing FreeBSD 6.2, the kernel that booted from the install CD was 
 GENERIC, but after the installation, the bootup showed that the kernel being 
 used was SMP. Being that my computer is a single processor, shouldn't it 
 default to the GENERIC kernel after installation, unless I request otherwise?
 
 Thanks,
 Joe
