I really wouldn't know where to begin debugging this. Suspend/resume isn't really something I know much of, all I can say it that it works on my laptop. Rafael, any idea where to start looking for this? > Link to actual bug report: > https://bugzilla.kernel.org/show_bug.cgi?id=195471 No, _this_ is the actual report, that is a random website you put stuff on.
