Here is a dmesg: https://gist.github.com/rzwisler/05e52020e87f0ccd6185182be999dae0 I was testing at this commit: 3c1f3ab219e5f xhci: handle halting transfer event properly after endpoint stop and halt raced. Turning on ftrace makes it much harder to reproduce. Should I keep trying for a repro with tracing turned on, or is the fact that it still happens informative enough to know we have to look elsewhere for a solution? Thanks, - Ross
