Hi Anant, I see you are testing lots of USB bugs. USB subsystem is currently broken, testing of any USB bugs will give false "no crash" results, see: https://lore.kernel.org/linux-kernel-mentees/CACT4Y+YmbmrH9gCCnCzP-FYa-dKxx9qhKZ+RQxi1f-+Hoj1SUg@mail.gmail.com/ _______________________________________________ Linux-kernel-mentees mailing list Linux-kernel-mentees@lists.linuxfoundation.org https://lists.linuxfoundation.org/mailman/listinfo/linux-kernel-mentees ^ permalink raw reply [flat|nested] 6+ messages in thread
