Hi,
Since I have upgraded to 2.6.22.1 from 2.6.20 I have problems with
Samsung disks. Sometimes the disks stall for about half a minute and
then I have these messages in the logs:

I also have two Maxtor disks on the same controller but they are working
correctly in ADMA mode. I now disabled ADMA mode and that seems to help.
hdparm -I output for the misbehaving disks (they're identical):
