Some of the bug reports were reporting success on my Red Hat derived
kernels (which include the PlanetCCRMA patches) even before I turned
LOLAT off, and I myself never had problems with LOLAT on HT smp
machines. Perhaps some of the PlanetCCRMA patches cure part of the
problems?

But there were some ATrpms users still having problems on smp asking
to turn off LOLAT for smp (only), and I did so. Just a few days later
LOLAT was turned off in the Red Hat kernel altogether, and I simply
copied this practice. The ll patches there are adjusted by RH, so
there may be some distribution specific bug, that the CCRMA 2.4.26
kernels will never see.

I agree. We should start thinking about and investing in 2.6.x
instead. :)
