I may not have your solution, but a couple of points: - kswapd, bdflush, klogd _may_ be your problem. - do you really want portmap, inetd, xfs, and sshd running on a laptop?!? I can see inetd (my exim seems to need it), but if you never ssh _into_ that box, you don't need sshd. You don't need portmap except if you're connecting to NFS, and xfs seems a waste of resources on a small box except if you're running apps that demand its abilities. fwiw. -- Any technology distinguishable from magic is insufficiently advanced.
