Died even faster this time. Yeah, and your other lockups haven't even been TLB related. Not that they look like anything else *either*. I have no ideas left. I'd go for a bisection - rather than try random things, at least bisection will get us a smaller set of suspects if you can go through a few cycles of it. Even if you decide that you want to run for most of a day before you are convinced it's all good, a couple of days should get you a handful of bisection points (that's assuming you hit a couple of bad ones too that turn bad in a shorter while). And 4 or five bisections should get us from 11k commits down to the ~600 commit range. That would be a huge improvement.
