Hello Rhys and Larry, at all, I am writing just to thank for the help. After a dark period I could install the hugemem and the problem disappeared. The wa indices in top fell to acceptable levels and the machine is having a better performance but still well lower running the gentoo livecd. As the problem was solved, I had to recover all the work that was delayed, and I have not had time to investigate the .config of the two kernels, but I will do it. As soon as I finish this, I will inform you of my conclusions. Thanks again. Eduardo Bach P.
