    Hi,
    This is pretty basic question which has been allready discused here but
    i can't find answer .On my workstation i use linux and freebsd linux
    works fine without any errors but freebsd shhows numerous errors and i
    don't know what to do.
    I test freebsd 5.2.1-released ,5.3 released then 5.4-beta1-released in
    all releases i got these error messages which crashes my system down
    with kernel panic
