Could you > please try reverting that commit and report back? Hi Paolo/Jianlin, I cloned the original job and was unable to reproduce the panic, I also don't see it for any previous or succeeding pipeline for stable tree. I setup a check to automatically tag the related pipeline in case we're able to reproduce it. We can also work on testing with the patch reverted, if we see it again we'll follow up in this thread.
