Title: TechnoTrend TT-TVStick CT2-4400 (v2) stopped working with kernel 4.18 Status in linux package in Ubuntu: Confirmed Bug description: Dear developer(s), I used a vdr-installation on Debian testing, before. Switched over to Ubuntu since the release of cosmic because of problems with GPU/steam under Debian. Now, I have problems to configure vdr because my TV stick doesn't seem to work with kernel 4.18. This is what I did: Installed Ubuntu, upgraded via aptitude to the latest packages, got the firmware "dvb-demod-si2168-b40-01.fw" and "dvb-tuner-si2158-a20-01.fw" (as it was recommended by *I guess it was* openelec.org and the modinfo output of si2168 and si2157), tried w_scan and failed (w_scan *can* find some signals but failes in getting the channels). That looks like this, f.e.: […} Scanning DVB-T2... 474000: (time: 01:38.796) 482000: (time: 01:43.155) 490000: (time: 01:45.163) signal ok: QAM_AUTO f = 490000 kHz I999B8C999D999T999G999Y999P0 (0:0:0) Info: no data from PAT after 2 seconds deleting (QAM_AUTO f = 490000 kHz I999B8C999D999T999G999Y999P0 (0:0:0)) […] Now, I tried an older kernel - 4.15, because it's still in the cosmics' repository and tried w_scan again: Success, although the TV- Stick doesn't find all the channels I found with Debian Testing. So, maybe there's a regression in the latest kernel regarding the TV- Stick-driver or there is another firmware which will work better with 4.18…? Would be glad if someone could help to work that out… Greets!
