Can people please test the following patch also available at http://www.FreeBSD.org/~jhb/patches/mlx.patch It fixes problems when using older Mylex controllers in Alphas, but I'd like to make sure it doesn't break mlx(4) for other folks before committing. Mike Smith has given the patch a once over as well. Thanks.
