I think the b89193e0b06f revert is needed to > fix the hang. If you care, the dmesg after resume: Our messages crossed looks like. Yes this problem needs to be fixed in stable. Reverting b89193e0b06f is definitely an option, however I think we might see problems on other devices. b89193e0b06f fixed problem on KWorld stick I have. Mauro said b89193e0b06f is causing problems on some USB ehci/xhci drivers. Let's go ahead and revert it for now. I will work on getting this reset_resume sorted out with the solution I proposed in my previous email. I hope it is okay to take you up un your offer to test. thanks, -- Shuah -- Shuah Khan Sr. Linux Kernel Developer Samsung Research America (Silicon Valley) shuahkh@osg.samsung.com | (970) 217-8978
