And the failures started to appear on 20180806 when I did the big KVM update from 85eae57bbb0612387201635659be543aaac2109e to 8c154ff6ee99d2d467c3c964ef6a478ca7614155.
They all seem related to some use-after-free on exit, and there is a reproducer at https://syzkaller.appspot.com/x/repro.c?x=122d6672400000, but it doesn't immediately cause the failure for me.
