AirStar HD-5000 with 2.6.20+ kernels

I have an AirStar HD-5000, and I'm having some trouble with newer
kernels.

I've read the wiki page (and updated the "User Experiences" section).
http://www.mythtv.org/wiki/index.php/Technisat_AirStar_HD-5000

It works great with 2.6.19.7, but I would like to upgrade due to issues
with unrelated features. Unfortunately, it fails to tune with any newer
kernel. I've tried several kernels from 2.6.20 through 2.6.22.1, all
with no luck.

There is a reference to changes with 2.6.20 reporting more accurate
signal information; could this be related?

Is there some kernel configuration setting that I might have wrong? Is
there some Myth setting that could be related to this problem?

I'm running the subversion level 14073 from late July, if that matters.

I'm also having a problem with my HD-5000 on a 2.6.20 kernel in Ubuntu
7.04. I can see it in lspci as a network controller I believe, and I
load the modules without error, but /dev/dvb/ is never created.

I haven't had a whole lot of time to investigate this problem due to a
recent misshap involving an overflowing fish tank which was apparently
placed too close to a shuttle frontend .....

I'm wondering if /dev/dvb/ is still on your system, but left over from
the 2.6.19 kernel....

There is a bug in the DVB drivers that prevents HD-5000 from working in
some recent kernels. It is fixed in 2.6.23 and it may be fixed in 2.6.22.7

See http://linuxtv.org/hg/v4l-dvb/rev/0277da58bf56 for the description
and patch that you can apply yourself if you have older kernel.

I'm running plain kernels, and I compile everything in--no modules
except for ivtv and nVidia. Under 2.6.19.7, lspci reports:
01:07.0 Network controller: Techsan Electronics Co Ltd B2C2 FlexCopII DVB chip / Technisat SkyStar2 DVB card (rev 02)

I don't know why it says it's a network instead of multimedia card, but
it works. When I was experimenting with newer kernels, the /dev/dvb
directory was populated by udev correctly, and Myth could find it in the
setup; it just couldn't tune it.

I'm guessing that you're missing some modules; I think you're further
away from success than I am. I'm not familiar with Ubuntu kernels, but
distribution kernels usually do everything as modules.

Here's the relevant portion of my kernel configuration:

CONFIG_DVB_CORE=y
CONFIG_DVB_CAPTURE_DRIVERS=y
CONFIG_DVB_B2C2_FLEXCOP=y
CONFIG_DVB_B2C2_FLEXCOP_PCI=y
CONFIG_DVB_FE_CUSTOMISE=y
CONFIG_DVB_LGDT330X=y

I'm not sure what else you need to set, and as I don't have it working
perfectly, I may be missing something.

Weird, I'm running ubuntu feisty 2.6.20-16 kernel and I have no
problems recording on my Airstar HD-5000/air2pc card.

When I do lspci, I too get the networking classification:
01:07.0 Network controller: Techsan Electronics Co Ltd B2C2 FlexCopII
DVB chip / Technisat SkyStar2 DVB card (rev 02)

But, myth records with it just fine. Also, /dev/dvb exists for me...
I'm running the vanilla packaged kernel.

Thanks!
Matt

Are you sure it's a vanilla kernel? 2.6.20.16 is a valid kernel
(released on August 16th, it appears), but 2.6.20-16 would be a
distribution kernel. It's possible that the fix was included in
2.6.20.16, as that kernel didn't exist yet when I was testing, and it
wouldn't be surprising if the fix were included in a distribution
kernel. But looking at the changelogs, I don't see the fix in any
kernel except 2.6.23-rc3-git8, which is part of 2.6.23-rc4.

Sorry, I meant to clarify that it was the standard distribution
kernel. Feisty shipped with 2.6.20-15, and an update was released to
2.6.20-16. I have not recompiled the kernel myself. I used to have
to do it all the time, but I don't have to do it on any of my boxes
anymore... just nice to use the distribution as is without issues.

Thanks!
Matt

I can confirm that that fix was exactly what I needed.

I'm having trouble with 2.6.23-rc4 with the nVidia drivers, but now I
can use 2.6.22.5, which should be good enough for now.

Thanks!
