Re: Installer login broken (ncurse?)

    Well, timeouts are often related to interrupt routing issues.  The code
    in both our tree and the FreeBSD tree is quite old, and looks 
    unmaintained.  I only see one code fix in the FreeBSD tree that might
    have an effect.

    Try the patch below and see if that helps.  It would also be useful
    to get the dmesg from a verbose boot of the CD, and pciconf -l output.

    Also, download a FreeBSD-current ISO and see if *it* can talk to your
    disks via the mpt device.

    If this patch doesn't do it we may be S.O.L. until a developer can get
    his hands on a similar system and figure out what the problem is.  If
    the FreeBSD CD can talk to it then its likely to be related to
    interrupt routing (we are somewhat behind in that area).
