I know that -next20181005 works ok, and I know -next20181010 is bad. Is there easy way to bisect using that information? I can do bisect between -next and mainline, but that's a lot of patches and thus not much fun :-(. In the meantime, I reproduced the failure with T40p. Is there someone with working x86-32 in -next?
