Is that even _expected_ to work? If you have x86 built first, I'd almost expect you to have to do "make ARCH=x86 mrproper" before building another ARCH. I don't see how ARCH=um would know how to do a full clean up of ARCH=x86, unless this is somehow arch-independent? Or maybe that's not an issue with other architectures because UML is special in that it uses parts of x86? Though I guess the patch here should make it do that, more or less, but it can't, likely because you're also switching from in-tree build to O= build? johannes
