oh....

So, you basically ran repair on a live, mounted filesystem; it's
expected that it would not be consistent at this point.

So, the errors you are seeing on this x86 are likely not related to
those you see on mips.  (the D state process might be interesting and
worth looking into, but probably not related to the problem you're
trying to solve.)
