Comment 83 for bug 550559

I'm actually running Debian Lenny (2.6.32-5), but I ended up here when googling for that "READ FPDMA QUEUED" error. I have an MSI K9AG Neo2 (MS-7368) motherboard with the following SATA controller:

00:12.0 SATA controller: ATI Technologies Inc SB600 Non-Raid-5 SATA

I have three disks in my computer:
* SAMSUNG HD204UI (SATA)
* SAMSUNG HD154UI (SATA)
* WDC WD800BB (IDE)

I started getting hangs during large file operations on the HD204UI and error spam in my syslog. I then moved both SATA drives to another controller card:

03:05.0 Mass storage controller: Promise Technology, Inc. PDC40775 (SATA 300 TX2plus) (rev 02)

After this it seems to work much better. I have a RAID 1 partition on the samsungs that failed hard to resync after rebooting with the drives connected to the mobo SATA controller. After moving them to the promise card it looks much better, I'm at 35% without any error at all. Before it bailed out after less than 10% because of errors.
