 I had a similar problem with a 790GX (the system from PR 39671).
 
 There were no problems when I installed NetBSD, because I changed the
 settings to AHCI before installing it.
 But at one point I changed it to SATA and then the FIRST disk (wd0) had 
problems.
 The second disk (wd1) had no problem (except for the point where wd0 was marked
 as failed in the raid set). wd2 was also in the system, but I had no partition
 on it so I can't be sure that everything was ok, but there were no errors from
 wd2.
