Your bisection result looks pretty nonsensical - not that it's impossible (anything is possible), but it really doesn't look very likely. Which makes me think maybe it's slightly timing-sensitive or something? Would you mind trying to re-do the bisection, and for each kernel try the mount thing at least a few times before you decide a kernel is good? Bisection is very powerful, but if _any_ of the kernels you marked good weren't really good (they just happened to not trigger the problem), bisection ends up giving completely the wrong answer. And with that bisection commit, there's not even a hint of what could have gone wrong. Linus
