So excluding them should be safe. One thing that I don't know about but always had in the back of my mind are Tegras, how those are handled or react. Looking at the vgaswitcheroo patches, these look like a really fine way to handle pm on these hda devices.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
