I was thinking originally fixing it by : http://www.spinics.net/lists/linux-kbuild/msg12036.html This fixed "properly" the make modules_install I think. And Marek pointed out that there were other cases, such as O=/my dir/ but not limited to, where it would also break, hence this patch. I'm not a kbuild expert so I'd like someone else (Marek) to enumerate the remaining cases not covered by the original patch. Cheers. -- Robert
