I've tried advice on turning off write caching, nothing has worked so far. The problem seems to be more intensive when heavy IO load exists... The system also spits out messages like this: free inode /usr/1655 had 4 blocks free inode /usr/44482 had 4 blocks and it has gone into panic and crashed after _extreme_ heavy IO. I'm down to one last option, being trying to run the drives at low speed with old 40-conducter cables, just to try and force this controller to slow down. It claims to be ATA-100, but when booted in windows, the driver is trying to run it in what it calls "UDMA mode 5", which to my best knowledge is ATA-133, which neither the drive (a 40GB Seagate ST340810A 5400RPM) or the controller supports. If anybody has had this problem in the past, please advise me... I don't want to go to 40-conducter cables to force it to slack off, but if there isn't another solution anybody can think of, I'm willing to try.
