Hi,

afer updating my Fedora server to the newest kernel 5.10.11, KODI starts having problems.
I access the media files by NFS. Not a local mount but via the integrated NFS implementation.
Up to 5.10.10 everything was fine, but now the video has glitches and skips frames every few moments.

If I play back the same media via a locally mounted NFS share, so with the means of the local OS (Fedora as well), the video plays fine. The same is true if I use KODI's option to access files directly via SMB on the same server.

It's a 18.9 build (Libreelec) and I verified it with a 18.9 build bundled with my Fedora desktop.

Can anyone confirm this behavior or even better, advise for solution? I don't want to rebuild my library by exchanging the URI from nfs:// to smb://

TLDR: known issue, looks like kernel regression.

Thanks for the hint. Didn't think to browse the obvious area for such bug reports.

I have two AndroidTV with Kodi, one Raspberry with LibreElec&Kodi and a intel NUC 10th gen. with LibreElec&Kodi. All are up-to-date.

I've also problems with stuttering video-playback. After updating my fileserver (runs Debian Bullseye), the problems appeared. Before the last updates, all was fine. Can't say what changed.
I'm not sure how your link can help me to fix the problem, even because I've two AndroidTV with Kodi - there I can't compile something or mount paths manually. 

As a quick-fix I used the smb-shares instead the nfs-ones, and on the NUC I mounted NFS manually.

On which side persists the problem? Client or server? I thought the libnfs has trouble with newer nfs-server versions?

For the records. I builded a new kernel on my server and the problem disappeared.
Here a little documentation how:

cpp:




apt-get install linux-source-X.XX

apt-get instakk libdev libelf-dev libssl-dev m4 debhelper dpkg-dev dwarves

mkdir ~/kernel

cd ~/kernel

tar xavf /usr/src/linux-source-X.XX.tar.xz

cp /boot/config-X.XX ~/kernel/linux-source-X.XX/.config

nano ~/kernel/linux-source-X.XX/.config

### change CONFIG_SYSTEM_TRUSTED_KEYS=""

### change #CONFIG_SYSTEM_EXTRA_CERTIFICATE



cd linux-source-X.XX

make oldconfig



nano net/sunrpc/svcsock.c

### change @row 1113 see link below 



make -j 3 deb-pkg LOCALVERSION=-yournamehere KDEB_PKGVERSION=$(make kernelversion)-1

cd ..

dpkg -i linux-image-X.XX-enzephalon-1_amd64.deb



reboot
