I set up some devices to test reboot this morning against Linus' master branch. Two devices out of 5, were already hang for that without your patch, but the other 5 are still work with your patch. Will update the result tomorrow morning. I think your patch solve this. Thanks. Tested-by: Shawn LinThanks, Bart.
