>Description:
Ok, using 120GB WD Drives, WD1200JB-00FUA0/15.05R15, 2 of them, ASUS A7V880 Motherboard (also, A7V600-X Motherboard), get lots of WRITE_DMA failed messages from AD0. Eventually, system panics. Tried only 1 drive on a cable (IDE controller), it;s actually worse, also get READ-DMA errors, UDMA ICRC errors, etc. Both drives on one IDE cable (Master/Slave) runs for around an hour before panic. 

I see lots and lots of other people with similar problems. Apparently, many of them run fine with FreeBSD 4. I do not have a 4 box. I tried numerous permutations of BIOS settings to no avail. Only solution is hw.ata.ata_dma="0" to disable DMA. 

This hardware worked fine on an ASUS A7V133 motherboard running 5.2.1, and, when updated motherboard to a ASUS A7V600-X, problems occurred. Thinking it might be hardware (motherboard), went to a A7V880. Same issues. Here's the pciconf output:

>How-To-Repeat:
      Not much to do, simply, boot or try to install. I have seen some reports that say that drives of 80Gb may work with this hardware.
