For the record, I'm told there's a patch for this reversal: https://marc.info/?l=openbsd-bugs&m=152802593705776&w=2 , which was in posted in response to: https://marc.info/?l=openbsd-tech&m=152796704214156&w=2 (Steele) , and it also helped with: https://marc.info/?l=openbsd-tech&m=152821522023626&w=2 (Popovski) After patching my tree and noodling for a few more hours with emacs, firefox and chrome, the witness report hasn't reappeared. cheers, Richard. > > lock order reversal: > 1st 0xffffff0009fe22f8 vmmaplk (&map->lock) @ >
