Priority: medium
Bug ID: 67800
Assignee: dri-devel at 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 at 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?
