[Bug 53757] Re: Slow 2D graphics and high CPU usage when idle

[matthew]

I believe the problem exists because both the -686 and the -686-smp
kernels in the repos are compiled for smp processors. I had the same
problem. I guess the best solution would be to go back to having the
regular -686 kernel NOT include smp support and have that only in the
-686-smp kernel.
