It's important to note that even if I did make a mistake during the
bisection process (and I certainly wouldn't discount that), recent
kernels still fail: but when I take out that commit from a recent
kernel, it fails.
I put in Andrew's suggested patch (to help find things), and now I
repeatedly get the problems in the attached log.
Not being an x86 knowledgeable person, I'm a bit concerned about the RSP
value?! (I enabled stack overflow checking, but that didn't stop things.)
