The AMD SB850 is a relatively new Southbridge chip, SATA3 AHCI at that.
Are you using AHCI mode? I'd take a deep look in demsg output and in
/var/log/kern.log for any errors relating to SATA, AHCI, mdraid, etc.
Quite often when drives are kicked offline it is a result of timeouts
and/or other errors on the SATA channels. The log information may help
narrow down the cause, whether a Southbridge problem, driver problem,
mode setting problem, drive firmware problem, etc.
For instance, the SB850 has 6 SATA3 ports. If the drives are SATA2, and
something is buggy in firmware on either end, there could be a link
speed negotiation problem causing problems. Manually forcing the link
speed to SATA2 may help in such a situation. You may also want to try
using native SATA/IDE mode instead of AHCI if you're currently using
AHCI. If not, you may want to try AHCI mode.
Regardless, find the errors in your logs and post them to the linux-ide
list for help.
