Priority: medium Bug ID: 67800 Assignee: dri-devel@lists.freedesktop.org Summary: Computer freezes after idle for several hours with dpms off (trinity) Severity: normal Classification: Unclassified OS: Linux (All) Reporter: laszlo.kertesz@gmail.com Hardware: x86-64 (AMD64) Status: NEW Version: DRI CVS Component: DRM/Radeon Product: DRI
I use Debian 64 bit and now i have the 3.11rc4 kernel installed, with mesa from git, xf86-video-ati from git, libdrm from git, all firmwares put in /lib/firmware. The hardware is A8-5500 desktop APU with its built in 7560D card. The system works very well, opengl, vdpau is functional.
I have xscreensaver set to turn off the monitor after 4 minutes, which it does. I can wake up after a few minutes by moving the mouse or pressing a key.
All is going well until i leave the computer for a longer time (it varies, usually a few hours) - the computer becomes totally unresponsive, doesnt react to keyboard/mouse and network wise is totally dead. The fans are on normally, no disk activity. I have to reset it from the reset button. Nothing out of the ordinary in any logs, they just stop logging, presumably when the computer freezes.
Now if i disable dpms and leave only blanking, this doesnt happen (This is why i think it has to do with the kernel driver), but this mean the monitor is on all the tme which isnt good since the computer runs 24/7.
PS. It didnt happen previously with the fglrx driver in any circumstances.
Any ideas why this might happen?
