I have many such snippets, but they are all similar in content. It does seem odd that it's always ata3&ata4 that fails together, and ata5&ata6 together at other times. This is primarily what leads me to believe it's a chipset issue.
I've tried so far:
Replacing the SATA Cables
Changing BIOS settings [RAID/AHCI/off]
Forcing legacy SATA Speeds by boot directives: libata.force=5:1.5G
Things I'm still trying:
Turning off any HDD feature I can find (ncq, etc)
But I don't think that's going to solve my issue, and even if it does, at perhaps too great a cost.
I don't think the HDD's are at fault, since they are relatively new, it's not always the same drives that fail, the SmartCHK and all other tests return fine, I haven't lost any data, they fail in 2's, etc.
If none of the kernel options help and if it has a free PCIe slot you could get a cheap Asmedia 2xSATA III controller card (ASM106x chip). They cost around $15 and work fine in Linux. I have three of them, one onboard and two cards, to provide me enough SATA ports for 7xHDD, 1xSSD, DVD, eSATA, Hotswap-bay... Using a different controller could take some load off your onboard one and verify your theory whether it's the onboard controller at fault.
I'll keep that in mind. Progress since last post is that I've disabled NCQ in the boot directives and I'm up 24hrs so far without a crash. This morning I restored full SATA speed to 3gb/s, so the only change in effect is NCQ off.
If I stay up for a week I'll declare the culprit found and post my findings here. Other posts on the net do lead me to believe NCQ on nForce chipsets are a bit dodgy, but nothing directly relates to the issues I find.
I'm still hopeful that someone reading this can help me fix the problem (once I find it), instead of just working around it by turning off features.
