Greg,
this concerns the Debian bug report
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=538410 on the atl1c driver:

Please merge the following commits into the stable tree for 2.6.30:

0ed586d075ef65c0268982e5b7f36d0ffaa95547
c5ad4f592e27d782faea0a787d9181f192a69ef0
37b76c697f4ac082e9923dfa8e8aecc8bc54a8e1

Tristan Charbonneau confirmed that these fixes - as present in 2.6.31-rc4 -
fixes the problem on his hardware.

Cheers,
        Moritz
