I won't say VM is perfect, but you can't know if it works better for you like it does for me until you try it. Upgrading a kernel is a pretty quick and painless job. As to the corruption, I don't see enough below to make a start as to the cause. David Brian Strand wrote: > Do either of these kernels fix the "2.4.x VM suckage" problems?
