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. http://unix.derkeiler.com/Mailing-Lists/FreeBSD/current/2004-08/2745.html 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
