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@xxxxxxxxxxxxxxxxxxxxxx
Reporter: rlk@xxxxxxxxxxxx
QA Contact: qa-bugs@xxxxxxx
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.
