Kernel oops when running tvheadend

[tordyvel]

HW:
- Asrock ION 330HT-BD
- Tuner TBS5922
SW:
- Openelec with kernel 3.6.6
- tvheadend 3.1.694 (I've tried earlier versions with same result)
- TBS Linux driver v121105 (I've tried with earlier versions with the same result)

At start the tuner loads it's firmware everything looks fine.
However when I enable tvheadend I get a kernel oops.
If i restart without the tuner tvheadend starts normally, although inserting the tuner again will not make it available in tvheadend.

Has anyone else seen this or have a workaround?

Hi tordyvel.
Did you try tbs6925 with other software like szap-s2 or kaffeine or vlc?
Did you try starting your pc with tbs5922 conected or conecting tbs5922 and restarting tvheadend?
When tvheadend is running, this have listed dvb adapters in "Configuration -> TV Adapters"?

Best regards.

[tordyvel]

Hi and thanks for the reply,
I haven't tried the tuner with other software on the OpenELEC distribution.
It's a minimal distribution with small possibilities to add packages...

I've tested to have the tuner connected at boot and enable tvheadend, kernel oops.
I've tested to have the tuner disconnected at boot, later connect it and enable tvhedend, kernel oops.
I've tested to enable tvheadend, later connect the tuner (no oops but the tuner doesn't show up in tvheadend), restart tvheadend, kernel oops.

Whenever tvheadend finds the tuner a kernel oops occure which will also crash tvheadend.
Thanks
TordYvel

does it work with other application than tvheadend like 'szap-s2' and 'scan-s2' included in the driver package? have you tested the box in other Linux installation. there are no any other similar complains and thus the only other thing i can suggest is to clean all DVB drivers from your installation with:

# rm -rf /lib/modules/<kernel_version>/kernel/drivers/media/

where of course "<kernel_version>" is replaced to correspond the correct path in your Linux installation and then re-install the drivers with "make install".

[tordyvel]

The distro I'm using is OpenELEC which cross compiles on another machine and creates an image to load.
So there is little options to adjust anything on target.

I've now tried with Ubuntu 12.10 and compiled the same drivers (this time on target) and using a slightly newer tvheadend (3.2.18) and now it works.

I'll try to add that tvheadend version to my OpenELEC image.

I still want to use OpenELEC though since it's a very stripped distro which ease the load on my Asrock 330.
I'd like an comment on what has happend leading up to the oops (maybe i'ts been called in an erronous way).
Thanks
