This bug seems to keep coming back. There have been at least 3 PRs about it, kern/47648, kern/81147, and kern/90167 . I thought it was fixed with the information in kern/47648, but as it turns out, it's still present in 4.11-RELEASE (just confirmed this). I guess the tests I performed in kern/47648 on 4.9 did not cover all scenarios, or there was a regression between 4.9+those minor patches and 4.11. I don't know the protocol for this -- would the old PRs be re-opened, or should a new PR be filed for 6.x?
