So since we are at -rc5 I think considering just reverting the patches and figuring out what's going on separately without exposing general users to these issues is a fair question... Note that the problem affects already 4.20 so -stable needs to be included regardless how you decide to solve these issues. -- You are receiving this mail because: You are watching the assignee of the bug.
