A change to drivers/media/dvb/frontends/tda10086.c that seems to have been made somewhere between release of 2.6.23 and 2.6.24 breaks support for my DVB receiver. dmesg shows no interesting output, however it is not possible for applications to display or switch channels.
The problem has been mentioned on the linux-dvb mailing list. Reverting the change resolves the problem. I checked by using tda10086.c from the Debian 2.6.22 source package. Upgrading to 2.6.25-rc8 from http://kernel-archive.buildserver.net/debian-kernel/ also helps.
Output from dmesg about my hardware:
dvb-usb: found a 'Pinnacle 400e DVB-S USB2.0' in warm state.
dvb-usb: will pass the complete MPEG2 transport stream to the software demuxer.
DVB: registering new adapter (Pinnacle 400e DVB-S USB2.0)
registering frontend 0 (Philips TDA10086 DVB-S)...
dvb-usb: Pinnacle 400e DVB-S USB2.0 successfully initialized and connected.
usbcore: registered new interface driver dvb_usb_ttusb2
Post on the linux-dvb mailing list:
Linked patch that broke the driver:
I don't know what the kernel team's plans for 2.6.24 are, but if it will be in testing for longer or if testing is even going to be released with this kernel, please consider fixing the bug in 2.6.24.
