Hi Jerry, Would it be possible for you to try out the patch contained here: https://github.com/openzfs/openzfs/pull/421 ? A direct link to the diff (as opposed the review/comments) is here: https://patch-diff.githubusercontent.com/raw/openzfs/openzfs/pull/421.diff
When developing that change, I remember hitting a panic that looks similar to what you reproduced, but wasn't able to trigger that same panic after my changes stabilized. Since I haven't root caused your panic, I can't say that my change will definitely address the panic, but I think it will. In addition to addressing the panic, it should also improve latency of ZIL operations (that was the original motivation for the change). It'd be great to get some additional testing from others before submitting the RTI to get it into illumos/openzfs.
