Running "make -j4" on a 2-way machine with 2.6.20-rc3, top shows
processes being scheduled only on CPU 0. CPU 1 is always idle.
This was reproducible with 2.6.20-rc[23] on a500 and rp3440.
I've verified this bug doesn't exist on 2.6.17-pa6.
I need to retest with something more recent (ie 2.6.19).

So I'm pretty sure we have a general scheduling bug and the above comments
suggest these might be related problem...no evidence of course.
Ideas on where I might start looking for the general bug?

thanks,
