Created attachment 105760 [details] dmesg with radeon.dpm=1 I have read that for this AMD A4-5300 APU (Aruba), radeon.dpm=1 on the grub command line of the kernel booting is useless because this option is already per default in the kernel. But if I don't use this option, Debian 7.6 reboots randomly after some minutes, hours or days of work when I use Iceweasel/Firefox and some flash animation, Libreoffice or other heavy application. With this option, no reboots. All work fine after several days. This issue seems about the same as https://bugs.freedesktop.org/show_bug.cgi?id=82201#c26 but I am not sure. I report this issue because dpm=1 should be useless.
