HPS, Just to give a quick status update, this patch has most certainly resolved our spin lock held too long panics on stable/10. Thank you to JHB for spending some time digging into the issue and leading us to td_slpcallout as the culprit, and HPS for your rewrite. I had heard rumors of other being affected by similar issues, so this seems like a fine candidate for an MFC if possible.
