A few minutes after starting live tv the picture freezes and helix don't work anymore. Restarting xbmc helps, but from time to time the problem occur again. I use all the latest builds from the wsnipex ppa (xbmc-fernetmenta-master and vaapi) follwing the instructions from http://forum.xbmc.org/showthread.php?tid=165707.

xbmc.log:
http://paste.ubuntu.com/8617659/

Is there anything that i can do to solve the problem?

looks like the how-to is not up-to-date. you should newer kernel ans mesa.

I cannot see all the versions you are running, cause this is not a Debug Log.

Try to upgrade your kernel:

Code:
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.17.1-utopic/linux-headers-3.17.1-031701-generic_3.17.1-031701.201410150735_amd64.deb http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.17.1-utopic/linux-headers-3.17.1-031701_3.17.1-031701.201410150735_all.deb http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.17.1-utopic/linux-image-3.17.1-031701-generic_3.17.1-031701.201410150735_amd64.deb

afterwards:

Code:
sudo dpkg -i *3.17.1*deb

followed by:

Code:
sudo reboot

Then retry. Next time, post xbmc.log with debugging turned on and all the other logs the original howto you followed wants to have. Is that wireless setup?

thanks for the quick replay fernetmenta. which kernel and mesa version would you recommend? can you advise me where i can get the mesa driver?

@fritsch
sorry did not saw your post as i wrote my feedback. no, no wireless setup, but gigabit ethernet. i will try that and post the results here. should i upgrade the mesa driver to (and when yes how)? thank you!

Quote:19:22:56 T:140131105195968 NOTICE: Host CPU: Intel® Celeron® 2955U @ 1.40GHz, 2 cores available

In -> Video -> Acceleration, please disable "Prefer VAAPI Render Method" - does this help?

We have enormous amount of chrombox users with the celeron 2955U that have a problem like that - dmesg should reveal the real issue. And the above mentioned setting makes a difference for them.

@fritsch
i updated the kernel thanks your instructions. "Prefer VAAPI Render Method" is enabled yet. should i disable that function or does the kernelupdate helps?

**fritsch** · 2014-10-21, 21:38

You need to tell us :-)

Make sure you post the relevant logfiles when it hangs / freezes again.

hre1 · 2014-10-21, 21:43

Okay, i will observe my system and provide you with the full set of logfiles... Wink

let me thank you for the fast help!

FernetMenta · (This post was last modified: 2014-10-21, 21:46 by FernetMenta.)

please post the logs mentioned in the how-to when the problem occurs. in case the issue you observe is the gpu hang bug of the driver it shows differently on different hw. i.e. it does not show on my i5 and i3 test systems. but on my celeron 1820t in my living room I can't enable MCDI. I would get a gpu hang after a couple of minutes. "Prefer VAAPI Render Method" does only influence progressive material. None of my test systems shows any issue with progressive.

hre1 · 2014-10-21, 22:07

Primary i watch live tv. Mainly interlaced services (most hd). I try to by the zotac ci520 (i saw you use it too) but this system is sold out in germany yet. so i took a look in the forum an read that the 2955U should do a good job for my aim (live tv with hd services). So decided to take a brix GB-BXCE-2955. But truley i have mixed emotions. I tend to use a i3 but it is hard to find fanless system with a attractive price...

Do you mean for interlaces sources the "Prefer VAAPI Render Method" is not the way to go?

**fritsch** · 2014-10-21, 22:13

Just test it and post the logfiles when the issue occurs.

Testing is not about "thinking what could happen", but actually reporting what "just has happened".

This setting has absolutely no effect on interlaced material.

hre1 · 2014-10-21, 22:28

@fritsch
your absolute right, but i like to know what happen in the background to provide you with better and only necessary information. Wink

but o.k. debug logging is turned on. Blush

I think thats a gpu hang error mentioned from fernetmenta. Is there anything i can do? btw. "Prefer VAAPI Render Method" is disabled, and mcdi is enabled.

FernetMenta · 2014-10-22, 07:13

Yes, that's a gpu hang. and again "Prefer VAAPI Render Method" has no effect on interlaced material. THe only tihng that helps on my system is no to use vaapi deinterlacing.
