I meant in general, as we do catch a bunch of such problems. Those usually require some input and testing from people who understand the subsystem to create a reliable reproducer. For this particular failure, do you want to try out the patches I linked in the first email or should we waive them for now? >=20 > And if you can't reproduce it, why would you expect me to know what is > going on? :) >=20 Well you do know the kernel pretty well :) We also cc the test maintainers to help out if it's needed since they understand the failed area, though given the current situation around the world people's reactions might understandably be slower.
