I would be suprised if it was how you compiled the kernel or a change in a user-tuneable parameter that caused the problem. It was probably something that changed in your storage driver or the core I/O layers between the two kernel versions. I'm not sure what's the best way of getting the problem fixed. Complaining on the linux-kernel list might help. -- Ken Preslan <kpreslan@xxxxxxxxxx>
