    I have many reports the HPT RAID controllers cause kernels (RH 7.3
    install) to crash, unfortunately because the VIA IDE spits an unrelated
    warning message on many of the affected mainboards just before the HPT
    code crashes ...

    Well, this patch fixes two possible array overflows in the HPT code.
    There is quite likely a lot more of stuff to fix.
