FWIW, without a bisection I guess no developer will take a closer look
(but I might be wrong and you lucky here!), as any change in those
hundreds of drivers used on that machine can possibly lead to problems
like yours. So without a bisection we are likely stuck here, unless
someone else runs into the same problem and bisects or fixes it. Sorry,
but that's just how it is.
