D689 (Altobeam 8830/8831) not compatible to Linux 3.5+

ricoba

Just wanna share my experience for those who use Linux and DMB-TH USB sticks, My Mythtv + D689 were running fine in my Ubuntu box since 10.04 to 12.04 (Linux Kernel 3.2).  It's not working anymore after I upgraded to Ubuntu 13.04+ (Linux Kernel 3.5 and Kernel 3.7), with the following messages whenever the dvb frontend device is accessed by either mythtv or dvbsnoop:

I think the DVBv3 support breaks in the dvb driver since kernel 3.5, and since the altobeam driver was not updated since 2009, and no developer was working with kernel dvb driver team, I think we better stay to use kernel 3.2 at this moment.

I also got similar error as seen in dmesg for my mygica 8558pro. I've made some modification as a workaround in the v4l-dvb source code. It can be downloaded from:

http://www.sendspace.com/file/mzu3y1

Untar the tarball, then cd v4l-dvb, run make and make install.

I still don't know where to set delivery system properly, so I can't submit any patch to the v4l-dvb team to solve this problem permanently.

Thanks for the patched source code.  Let me test it with kernel 3.5.
