Thank you very much, Jun. One more thing -- we've made quite some changes in 2.2.1 so I wonder what would be the best way to upgrade. I'm thinking: 1> check out new kernel, use "merge directories" function from emacs, or 2> use "cvs import" to import the new kernel to our local cvs repository, then merge with our local changes by "cvs update/co -j".. Any comments/suggestions? Thanks! -Hua > > > > We made changes to linux/MIPS kernel 2.2.1 for our > > system and it's been running well so far. We now > > plan to upgrade the kernel to 2.4.X.
