Priority: medium Bug ID: 83505 Assignee: dri-devel@lists.freedesktop.org Summary: AMD A4-5300 APU : only radeon.dpm=1 prevents random reboots with 3.16.1 kernel. Severity: minor Classification: Unclassified OS: Linux (All) Reporter: rpnpif@free.fr Hardware: x86-64 (AMD64) Status: NEW Version: unspecified Component: DRM/Radeon Product: DRI
Created attachment 105760 --> https://bugs.freedesktop.org/attachment.cgi?id=105760&action=edit 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.
