I thought you wanted me to drop this one because the dependent/relevant patches were not pushed to stable at that time. But I re-read your email and I missed one important part that this particular patch is valid for a separate bug introduced in IRQ stack stuff in 4.11. I missed that important part. My apologies for that. Again. Greg please drop this one for both 4.4 and 4.9. Regards, Amit Pundir > > Cheers > James
