How would you recommend proceeding with this patch ? I can drop the
eee-broken-1000t property as I didn't notice any issue, or keep with the
risk that it my be cargo-cult. This is beyond my area of expertise, so I
can perform tests if I get clear instructions, but I don't think I can
investigate alone at this point.
