Hi List,

i would like to say a few words to this post. Since this Thread was
opened in the VDR ML and was switched to the DVB ML I will send it to
both Lists.

I get the same Message in my Syslog using Alsa 0.9.3 and V4L25/Bttv
0.9.6

First I was 100% sure you are right but after playing around a bit and
Using V4L1/Bttv 0.7.105 and still Alsa 0.9.3 the Problem was gone.
AnalogTV still Segfaults here and then with some specific channels but
I think that’s another Problem with V4L1. The Point is that there were
No more "alsa memory.c:131:null kfree (called from c26214cc)" in my
Syslog.

I never got this Message while listening to music or doing whatever.

Are you sure that its harmless since I *only* get this message with the
Combination V4L25/Bttv 0.9.6 and Alsa 0.9.3 and not while using V4L1 and
same Alsa!? After that Message I think *mp1e* Segfaults.

I do :)

I did switch to DVB Source 270403 too but no difference so i don't think
It has something to do with the DVB driver or the changes you made
regarding the MSP Detection.
Uwe are you sure you didn’t change anything else??? What kind of Analog
TV Card are you using?

I don't think so due to the reasons above. JFYI I am using a WinTV PVR
PCI
And this board has a more or less exotic MSP (MSP3415D-B3).
I would think that you are disturbing V4l25 if you are disturbing
anything
But since using an older driver dind`t change the behaviour here I can´t
be true. I will post some Logs below perhaps someone can see where the
Problem is.

Using V4L25/Bttv 0.9.6 here (funny while using gdb I can switch a few
times more!?!?!?)
