I think this is the same as the kexec issue that also hit -tip. It's *probably* fixed by the final series to actually enable 5-level paging (which I don't think is in -tip yet), but even if that is the case this is obviously a nasty bisectability problem. You migth want to verify, though. The second batch starts here: https://marc.info/?l=linux-mm&m=148977696117208&w=2 Hmm? In the meantime, this is currently -tip only, so I will stack back from this thread unless you can reproduce it in mainline too.
