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

I report this issue because dpm=1 should be useless.</pre>
