Priority: medium
Bug ID: 73619
Assignee: dri-devel at lists.freedesktop.org
Summary: XServer frequently freezes for a few seconds
Severity: normal
Classification: Unclassified
OS: All
Reporter: arichardson.kde at gmail.com
Hardware: Other
Status: NEW
Version: 10.0
Component: Drivers/DRI/R600
Product: Mesa
The XServer randomly freezes for a few seconds or sometimes even 1-2 minutes. I
cannot move the mouse, and the screen does not update.
I have a HD4850 card running on a
3.12.6-1.g080d0df-desktop SMP PREEMPT x86_64 kernel with Mesa 10.0.1 (both from
openSuSE packages). These freezes also happen with the default 3.11 kernel, I
upgraded in the hope of it being fixed, but the issue is still present.
These issues started after the upgrade to openSuSE 13.1 which has a 3.11 kernel
instead of the previous 3.7 kernel. The Mesa version did not change, I was
always running the latest released version. My guess is it has something to do
with the r600 kernel changes in 3.8+.
During these freeze periods I can ssh into my system and top shows no CPU
usage, so the XServer seems to be sleeping instead of being in a busy loop.
dmesg gives me no messages and /var/log/XOrg.0.log is also empty.
I don't know how to get any more detailed logging output. If you provide me
with the necessary environment variables/kernel parameters I will give you
these logs.
Not sure if this helps, but most of the time the freeze happens when I open a
new tab in firefox or switch to a different one. However it also happens at
random intervals using other programs.
It can sometimes take quite a long time until this freeze happens, however once
it has occured once, it usually happens again after a short timespan (1-2
minutes or even less).
Is it possible to debug the XServer just like a normal program using gdb? If
yes I will try to provide a useful backtrace once the next longer freeze
happens
