What SATA controller are you running? I think I've traced my
problems to the Silicon Image 3112 controller. There are known
problems with this chip which look like they have been fixed, but
only if you apply all of the latest patches (latest from 6/22:
http://marc.theaimsgroup.com/?l=linux-ide&m=108793699914304&w=2 )
From dmesg;
ICH5-SATA: IDE controller at PCI slot 0000:00:1f.2
ICH5-SATA: chipset revision 2
ICH5-SATA: 100% native mode on irq 11
From lspci;
0000:00:1f.2 IDE interface: Intel Corp. 82801EB (ICH5) Serial ATA 150
Storage Controller (rev 02)
I didn't build the box and the guy who did isn't around so that will
have to do for now
:)
According to the latest SATA on linux status report:
http://marc.theaimsgroup.com/?l=linux-ide&m=108422797301151&w=2
It looks like the ICH5 should work. I've only played with the Silicon
Image 3112 and a (just recieved) Promise TX4.
I have a buddy who's got an ICH system he's gotten RAID working on. It's
an intel system, although I'm not sure if it's ICH5 or ICH6:

You might also try using the libata drivers (makes the SATA drives look
like SCSI /dev/sdX instead of IDE /dev/hdX). They might be more (or
less) stable...
