Binary package hint: linux-source-2.6.22

I've a Lenovo T61 laptop with a SATA disk. Every now and then the disk freezes for 30 seconds and then I get this error in dmesg:

A thread on linux-kernel explains this error and has a patch for this error for a different disk model:

  * http://lkml.org/lkml/2007/6/6/15
  * http://lkml.org/lkml/2007/6/6/195

One of the posters there even has the same model disk as I have.
