Re: libata/sata errors on ich[?]/maxtor

[Ian Young <lkml@societasilluminati.org>]

I think I may have figured out my problem (I hope). I had, a while ago, 
upgraded my BIOS, which reset the SATA mode for the controller. It's odd 
that the error didn't pop up until I upgraded my drives from dual maxtor 
6Y160M0's...

Originally I had the controller set up in the BIOS as "RAID" instead of 
IDE, so they didnt' show up on any of the BIOS IDE channels in the BIOS 
Setup screen. After the BIOS upgrade, this was overwritten with "Auto" 
mode. When I first started having problems it was on "Auto"... I've set 
it to "Combined" and "Enhanced", to no avail. (though I may set it to 
"Enhanced" and reboot just to see what the kernel messages say.... ) As 
of now, I've re-set it to "RAID", and now the kernel outputs the 
following on boot. I have not had any issues since making this change.

Previously, on "Auto", this is what the kernel would output on boot:

lshw also shows the bus and IO memory organized differently, with these 
two options:

http://www.societasilluminati.org/hinv2.html : "RAID" mode set in the bios
http://www.societasilluminati.org/hinv.html: "Enhanced" mode set in the bios

Unfortunately, my boot logs have rolled since I got the "Enhanced" listing.
