DVB-C no EPG data with kernel v5.0-rc

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

I have a

03:00.0 Multimedia video controller [0400]: Conexant Systems, Inc.
CX23887/8 PCIe Broadcast Audio and Video Decoder with 3D Comb [14f1:8880]
(rev 04)
        Subsystem: Hauppauge computer works Inc. Device [0070:c138]
        Kernel driver in use: cx23885

on linux 5.0.0-rc8.

In dmesg I see lines like this:

[ 17.925917] tda10071 7-0005: found a 'NXP TDA10071' in cold state, will try to load a firmware [ 17.925920] tda10071 7-0005: downloading firmware from file 'dvb-fe-tda10071.fw'

...

The last line is repeated regularly.
I have noticed that vdr doesn't save something in epg.data, when I deleted the file and reboot, no new data is saved until I boot kernel 4.20 or older.

But: As far as I know I don't miss any channels.

Do you have any idea what the problem might be?

I could bisect if you want.

Thank you,

Thomas
