[Bug 1143148] New: dvbv5_scan and w_scan fail to scan for TV channels w/default kernel
http://bugzilla.opensuse.org/show_bug.cgi?id=1143148 Bug ID: 1143148 Summary: dvbv5_scan and w_scan fail to scan for TV channels w/default kernel Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.1 Hardware: x86-64 OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-maintainers@forge.provo.novell.com Reporter: rlk@alum.mit.edu QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- dvbv5_scan and w_scan, tools for scanning for TV channels (in my case, US ATSC), are able to lock tuning but not extract metadata using kernel 4.12.14-lp151.28.10-default on a Ryzen 2700X using a Hauppage HVR-950Q tuner (which worked fine on 42.3 and possibly 15.0). Packages I'm using for channel scanning: w_scan-20170107-lp151.2.3.x86_64 dvb-utils-1.14.1-lp151.2.5.x86_64 libdvbv5-0-1.14.1-lp151.2.5.x86_64 With kernel-default-5.2.1-2.1.gbf5c01b.x86_64, the scanning succeeds (hence I'm filing this against the kernel). w_scan emits the following error: tune to: 8VSB f=503000 kHz (0:0:0) (time: 02:52.484) (0.692sec): SCL Info: no data from PAT after 6 seconds Info: no data from VCT(terr) after 26 seconds Info: no data from VCT(cable) after 26 seconds I'm able to watch TV (using dvbv5-zap) just fine; it's only the scanning that fails. -- You are receiving this mail because: You are on the CC list for the bug.

Also, note that this is a regression, as it worked properly in earlier releases.
Which earlier release did it work? If you can install the kernel of that release and confirm whether it still works, we can narrow down the regression range. -- You are receiving this mail because: You are on the CC list for the bug.
