Control: notfound 771224 4.0.8-2 So i have been running 4.x.y series kernel for some time now, and i have not seen those traces in 4.x.y kernel so far. I believe it means that it was fixed upstream and bug can be closed accordingly. Thanks! PS: i do not know how to close bugs here, or if the first line of this mail is correct Roman. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
