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

href="show_bug.cgi?id=82201#c26">https://bugs.freedesktop.org/show_bug.cgi?id=82201#c26</a> but I am not sure.
I report this issue because dpm=1 should be useless.</pre>
