The splat doesn't always happen but the hang does seem to be reproducible. I have a sysrq+t during this hang here: https://drive.google.com/file/d/14qsIb3HNlSx91kPq1Uvo_IHnivQ3S3NO/view?usp=sharing Maybe there's a hint why we're hung up as a prelude to the splat even though I haven't gotten the warning yet... -- Chris Murphy
