Subject: sky2 patch in 2.6.24-rc7-git6 breaks POST - commit 84cd2dfb04d23a961c5f537baa243fa54d0987ac

Hi,

I have an Asus Commando motherboard, p965 chipset with Marvell
88E8056 and 88E8001 gigabit lan onboard. skge and sky2 are compiled
in.
When booting linux-2.6.24-rc7-git6, everything seemed fine, but when
attempting to reboot, the machine would freeze on POST, right before
detecting AHCI drives.
In order to get it to POST, a reset or shutdown from the power button
is not enough, I actually have to cut power to the motherboard using
the PSU's power switch!

I first thought that the BIOS or CMOS may have gotten corrupted, but
eventually I fund that linux was the culprit. After a git bisect, I
found the bad commit below

root@...-desktop:/home/ops/linux-2.6# git bisect bad
84cd2dfb04d23a961c5f537baa243fa54d0987ac is first bad commit

    sky2: remove check for PCI wakeup setting from BIOS

    The driver checks status of PCI power management to mark
    default setting of Wake On Lan. On some systems this works, but often
    it reports a that WOL is disabled when it isn't.

    This patch gets rid of that check and just reports the wake on
    lan status based on the hardware capablity.
