    I've got an American Megatrends Titan III PCI EISA Pentium motherboard
    from around 1996. I have two Pentium 166MHz processors (P54C) on it.
    I recently bought a brand new Promise FastTrak S150 TX2plus RAID
    controller and a couple of parallel ATA hard drives to go with it.

    I installed i386 FreeBSD-CURRENT 5.2.1 generic.
    If I did not configure any RAID arrays through the hardware BIOS on the
    controller card, the card was detected and the system would start.
    If I configured a RAID array in the hardware, the system would always
    reboot while probing the hardware.

    I wanted to be able to use the RAID capabilities of the card, and I
    thought an update might help, so I updated to the latest code I could get
    and rebuilt the world and the kernel, using the latest GENERIC
    configuration. This was yesterday 4/18, and I finished the process today
    4/19.

    I have the same problem, except that instead of a reboot when I have a
    RAID array configured, I get an error message during the mptable_probe:
    "Panic: mptable_walk_table: Unknown MP Config Entry 18
    at line 401 in file /usr/src/sys/i386/i386/mptable.c"

    For comparison, if RAID is not configured on the card, the system boots,
    but during the mptable_probe I get an
    "MP Config Table has bad signature: \^B"
    Then later when it gets around to detecting the RAID card, I see this:
    atapci1: <Promise PDC20371 SATA150 controller> port
    0xea80-0xeaff,0xefa0-0xefaf,
    0xee80-0xeebf mem 0xffac0000-0xffadffff,0xffaff000-0xffafffff irq 9 at
    device 11
    .0 on pci0
    atapci1: failed: rid 0x20 is memory, requested 4
    atapci1: Reserved 0x20000 bytes for rid 0x20 type 3 at 0xffac0000
    atapci1: Reserved 0x1000 bytes for rid 0x1c type 3 at 0xffaff000

    Running the mptable utility after the system has started doesn't yield any
    unusual results or the mysterious \^B signature.

    I've tried booting with and without ACPI, but there's no difference.
    Can anyone give me any troubleshooting advice? I am still very new to
    FreeBSD.
