That is one of the hills I am trying to climb.

All of my previous "good" kernels were 32 bit with or without PAE. The
important one is 2.6.32-122-rtai which is what it takes to run linxcnc,
which I need to do for simulation runs occasionally. That is what I am
booted to ATM, but its a poor kernel for busy desktops, not PAE because
that is a speed hit. We are fixing that, but it hasn't dribbled down the
hill to me yet, still "alpha" and these guys don't even want to ship Beta.

I've also found that, so my makefiles use -j3 and are ok AFAIK.

Like me, you didn't buy the superdooper overclocked version. :) This 9550
is running at about 2.1Ghz and seems happy as a clam doing it. I think
you'd call it cheap consumer stuff.................

I don't have any tarballs between 3.8.3 and 3.12.0 locally. Perhaps a
better starting point suggestion since I do know how to run gftp?

Yes Mike, I've been following your messages on this list for much of a
decade. Occasionally pretty pointed too. ;-)
