as it works well in 2.6.26,
can you run git bisect to see which commit introduces this regression please?

Here it is:

    sky2: pci power savings
    
    Turn on special bits to save more power when device is shutdown.
    Tested on a limited range of hardware, some of the bits are for
hardware that probably isn't even in production (like Yukon Supreme)
and was ported from the vendor driver.
