I didn't understood anything you sad, but never mind. 

In -rc2 there was a problem with massive iowait when anything was done
(starting an app, loading a web page, etc ...), and there was a massive
read operation from my /home partition. In -rc3 that stopped, and this
started happening. Maybe it is related somehow?

Or maybe, it is just some problem with nvidia blob and 3.7 kernel
loosing VM_RELEASE  (in a blob's mmap.c it was replaced with
VM_DONTEXPAND | VM_DONTDUMP ).  - or maybe I'm just saying nonsense
here.
