[linux-dvb] kernel: av7110(0): msp_readreg(<number>) failed : Siemens DVB-C analog modul

[Michael Meyer <mi_me@freenet.de>]

Hi,

I just tested new cvs version of 2.4 branch to use with my Siemens DVB-C rev1.5
with analog modul.

DVB input works fine.

Switching to analog channels results in "av7110(0): msp_readreg(<number>) failed".

I can watch and listen to analog channels for less than a second. The screen turns into
black-white snow after that.

It works fine with older cvs version.

Regards,
Michael Meyer

PS: Output of debug mode.
