Same as bug 1800238

[Ed Vermeulen]

With kernel 4.15 Ubuntu 18.04, I could display the tv stations with VLC. Not with kernel 4.18. As a second OS I have Linux Mint 19 (kernel 4.15), there everything works.

I tried linux-headers-4.20.0-042000rc2-generic_4.20.0-042000rc2.201811121328_amd64.deb, etc.
Dpkg ended with 'errors'.
Dmesg contained errors usb related where the DVB-stick is plugged:
[ 22.648722] usb 1-10: dvb_usb_v2: usb_bulk_msg() failed=-110
[ 22.648731] usb 1-10: failed=-110

[ 22.648750] si2168: probe of 19-0064 failed with error -110
The play-function with VLC did not work.

Previously, I installed Ubuntu 18.10 and then kernel 4.20. VLC 3.04 had no success. And w-scan gave no results.
Now, I installed Ubuntu 18.04.1 and then kernel 4.20. The kernel-headers failed to install. The play-function with VLC 3.03 did work well.
Perhaps it is not the kernel but something else. I am not an expert.

[Ed Vermeulen (ed-vermeulen)]

Problem solved in latest 4.18 kernel. Thanks.
