 Are yo using a localmodconfig like config? When I build kernels myself
 I'm copying a default distro's config and run oldconfig and if wanted, I
 add a few settings manually before running oldconfig. Building a kernel
 that way, on my aged machine takes around 90 minutes. Since a while
 back I usually install Arch kernels build by Joakim, instead of building
 them on my own.
 
Yes, using oldconfig, and afterwards menuconfig or xconfig, if I need to
tweak some more.
With this Quad core it just takes less then half a hour, running in
background.
Well, on the 3.4.xxx-rt kernels I could even build a kernel in
background, and play with guitarix for the time being, at 128
frames/period without any Xrun.  On later ones, I can't open a
text-editor without receive a Xrun.
