You could try to see if it fixes the issue for you. https://www.mail-archive.com/linux-media@vger.kernel.org/msg135901.html Sorry for the slow response. I have been running the 4.14 LTS kernel for a while now and forgot to check on this. I just tried out the 4.19.12 kernel as built by Arch Linux, and the TV tuner seems to be working fine. So it seems something between 4.19-rc2 and 4.19.12 has fixed or hidden the problem. But I am now running ZFS on this server, so the kernel is tainted. I guess it could be possible that that is somehow preventing the error from happening. Scratch that, I must have just gotten lucky the day I tried that. Arch has now upgraded their LTS kernel to 4.19.13, and the bug is happening again for me. It is also happening with the standard kernel, which is now at 4.20. Trying to build now with the patch. Looks like there is a v3 here, so I will try that one: https://www.mail-archive.com/linux-media@vger.kernel.org/msg136750.html I have tried the v3 patch and can confirm it works. I used the one from here since the mail-archive.com site seems to mangle tabs: https://www.spinics.net/lists/linux-media/msg143589.html I applied it to Arch's linux-lts 4.19.13-1: https://git.archlinux.org/svntogit/packages.git/tree/trunk?h=packages/linux-lts&id=000049803fe84a4cef272826e95733c3d4777dc8 That built and worked fine. I used it for watching TV for an hour or so while also building Arch's linux 4.20.arch1-1 kernel with the patch applied, so it seems stable. The patched build of 4.20 also ran fine for an hour or so. https://git.archlinux.org/svntogit/packages.git/tree/trunk?h=packages/linux&id=0a8cba33e3b8289624c6b9bf5aae6a9ce2c7cc16 Since 4.19 is an LTS release, please apply this patch there as well as mainline. Patch fixing it was merged upstream during the merge window and it is there for Kernel 5.0-rc1. The patch was also merged at stable trees for Kernels 4.19 and 4.20. |
