If you have bad hardware, you have bad hardware. :( Try disabling the external cache to see if your errors go away. If they do, then you have bad hardware and there's nothing that FreeBSD can do to work around it (yet, working on it now). If they don't then it's possibly bad memory chips. Do you get any NMI's? (The 1542 tend to hold onto the bus a bit longer than sum-optimal memory chips like) Nate -- nate@bsd.coe.montana.edu | Freely available *nix clones benefit everyone, nate@cs.montana.edu | so let's not compete with each other, let's work #: (406) 994-4836 | compete with folks who try to tie us down to home #: (406) 586-0579 | proprietary O.S.'s (Microsloth) - Me
