[linux-dvb] Possible tuner problem in current Hg

Hi,

Are there any known tuner problems in current Mercurial, particularly
with the saa7134 driver and/or the 2.6.25.x kernel?

I'm trying to use Janne Grunau's driver for the Hauppauge HD-PVR in a
system which also has a KWorld ATSC 115.  The HD-PVR driver works as
expected with it's many known issues but the ATSC 115 doesn't work
with Janne's driver.  Mplayer reports an inability to lock onto a
signal after 30 seconds when trying to use the ATSC 115.

To rule out any HD-PVR specific changes, I tried main-line v4l-dvb
drivers myself and got the same results on the ATSC 115 as with
Janne's version.  Most recently, I just tried the 2.6.25.14 kernel
with the following v4l-dvb tip revision.

    changeset:   8582:cbfa05ad2711
    tag:         tip
    user:        Mauro Carvalho Chehab <mchehab at infradead.org>
    date:        Fri Aug 01 08:23:41 2008 -0300
    summary:     set mts_firmware for em2882 based Pinnacle Hybrid Pro

I'm attaching a couple of short log snippets from when the saa7134-dvb
and required modules are loaded.  kern.log.good is from using the
stock v4l drivers from the 2.6.25.14 kernel and kern.log.bad is from
using the current v4l-dvb drivers in Mercurial.  The only differences
are the "tuner-simple" lines in the bad version.

Any help in solving this problem with the ATSC 115 is greatly
appreciated as it's a big inconvenience to keep switching driver
versions when changing between capture devices.  I can provide more
detailed logs or run additional tests as requested.

David
