Kernel: 3.16.0-0.rc4.git2.2.fc22.x86_64
MESA: 10.3-0.devel.1.f381c27c548aa28b003c8e188f5d627ab4105f76.fc22.x86_64

kernel spits out following each time cheese is run and camera turns on: (four times in this case)

Comment 1 Michel Dänzer 2014-07-15 04:04:42 UTC

Please attach the corresponding Xorg.0.log, preferably captured after the problem occurs. Also, any corresponding output from the cheese process would be interesting.

Comment 2 Shawn Starr 2014-07-15 13:14:48 UTC

This is what happens

When cheese is run Xorg log shows this info:

I note, for me, EXA is *still* default not GLAMOR, I have to override with a xorg.conf.d config to enable GLAMOR. If you'd like me to switch to GLAMOR, I'll do so and retry this all.

DDX: xorg-x11-drv-ati-7.4.0-1.fc21.x86_64

From cheese: no significant errors nothing related to video

Comment 3 Shawn Starr 2014-07-16 06:58:10 UTC

Additional info:

with EXA (default), when Composite is enabled you will see those errors from 
kernel

With EXA (default), Composite *OFF* no error msgs show, but cheese aborts frame updates from webcam

With GLAMOR enabled both with and without Composite in use, no error msgs show from kernel, Cheese aborts frame updates from webcam.

Comment 4 Shawn Starr 2014-07-16 06:59:45 UTC

In all the cases, cheese aborts frame updates and the camera shuts off to clarify.

Sounds like there is some kind of problem with the webcam, which is probably unrelated to the graphics drivers, and the kernel messages are just a symptom of that.

Comment 6 Michel Dänzer 2014-07-17 04:07:37 UTC

Since the kernel messages only appear when using EXA, they're probably caused by a bug in the xf86-video-ati EXA code.

But I really doubt that the webcam issues are directly related to the graphics stack.

Comment 7 Shawn Starr 2016-02-26 19:03:00 UTC

Doesn't seem to be an issue anymore, GLAMOR is now default.
