University of Colorado at Boulder

N/A      
>Description:
We have a Gigabyte GA-7DPXDW motherboard with the AMD 760MPX chipset, and the onboard Promise Fasttrack 100 IDE-RAID and maxtor 160GB drives.  When booting off the 4.6 CD, the install will panic during the boot process if the drives are left connected to the on-board promise ATA 100 IDE-RAID.  If we disconnect all drives from the onboard promise ATA 100 IDE RAID and only hook up a drive to the master IDE controller on the motherboard, we can boot up and install 4.6.  Then, when we reattach the drives to the onboard promise ATA 100 the system will crash during bootup after displaying several messages similar to the following (one line for each drive on the controller):
ad0 maxtor 4G160J8 Read command Timeout tag=0 serv=0 resetting   trying fallback to PIO mode
ata3: resetting devices
then kernel panic (on 4.5 it would boot up but these drives would be stuck in PIO mode and therefore terribly slow).

As indicated in the 4.6 release notes, we tried setting hw.ata.tags="1" in /boot/loader.conf to no avail.  Any help would be greatly appreciated.
>How-To-Repeat:
happens every boot.      
>Fix:
none known other than switching to linux which works with this onboard controller just fine (god forbid I have to switch - please help!)
