But the same hardware dies horribly on Gigabyte GA-965P motherboards.
Could you send me full lspci -vvx output. I'll re-enable it for Asus and add a block
for the Gigabyte boards. (sigh)

The following hardware on an Asus P5B Deluxe board worked fine with 2.6.20:

I guess it may come as a side effect of your upcoming patch, but it would be nice if sky2 could printk() some basic info when it detects one of the controllers that it is going to ignore. Right now it is kind of mysterious why eth0 has disappeared in 2.6.21 for some users. 

Thanks,
Daniel
