I cut a deal with my 8600 to get it to boot 2.6.27. It does not seem
to work right either.

The error message that shows up in dmesg is (the messages that show
up for the gigE appear to be for two different busses (hubs?):

A bug was introduced in 2.6.27 and the fix is queued for 2.6.27.stable.  
The fix takes the form of two patches, which you can find here:

http://mirrors.med.harvard.edu/linux/kernel/people/gregkh/gregkh-2.6/gregkh-04-usb/ohci-allow-broken-controllers-to-auto-stop.patch
http://mirrors.med.harvard.edu/linux/kernel/people/gregkh/gregkh-2.6/gregkh-04-usb/usb-ohci-fix-endless-polling-behavior.patch

The second depends on the first, so you have to apply them both.
