I am at the wrong point of this discussion, but i am talking with Novell 
about an issue about IO-Scheduling and i didn't find the OP.

Please try

echo cfq > /sys/block/sda/queue/scheduler
or
echo deadline > /sys/block/sda/queue/scheduler
or 
echo anticipatory > /sys/block/sda/queue/scheduler

Maybe there is a problem with the setup of the default scheduler, 
change "sda" to your device! ;-)

If this works you can add "elevator=deadline" or cfq, ... to your kernel 
boot options in grub.

Here is the bug link: https://bugzilla.novell.com/show_bug.cgi?id=267444
