Hi. I'm having this issue on Elementary and Xubuntu with the same card (HD6870), but Firefox doesn't need to be running.
Unity and Gnome apparently fixed the issue since vlc works really well. Does anybody know where could be the issue on Elementary. Setting the radeon.dpm=0 makes the problem go away, but i don't feel comfortable using it since it must put a lot of stress on the card. I'm using kernel 4.10 with the 16.04 hwe stack on all the distro's and only Unity and Gnome work out of the box. Thanks. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1574130 Title: radeon GPU lockup when using VLC and Firefox Status in linux package in Ubuntu: Expired Bug description: When playing a video with VLC and running Firefox at the same time, the radeon driver consistently (reproducibly) locks up and crashes on my machine since upgrading to 16.04. I'm using a Radeon HD 6870. This does not happen with other video players (totem, mpv). Tested with different video codecs and different window managers (gnome- shell, metacity).
