Hi, I recently updated to the new kernel 5.10.11.
After that, I observed problems with my Kodi installation which access media files via NFS. Movies would play, but are disturbed and skipping lots of frames.
I rebooted into 5.10.10 and the problem has disappeared.
I did not check whether SMB gives other results, so I will verify this as a next step.
Is there a known issue or something I need to adjust on my Fedora server?
OK, I used journalctl --boot to investigate the information around NFS. So far, I don’t see any warning or error message.
In the meantime I accessed the same file via SMB in Kodi and it played just fine under 5.10.11.
I didn’t test if writing to the NFS server will end up in corrupted files, maybe I will run some tests later.
I verified file access from another Fedora system with copying data from a local filesystem to the NFS share and I verified the integrity of the file with md5sum, both on the client and on the server: no violation found
I used VLC and Kodi to play the files from the locally mounted path (via NFS) on my system: no more glitches
Kodi uses his own libnfs implementation and accesses via URI like nfs:///, which causes glitches while playing back the media
Kodi accessing the same file with his own SMB implementation works fine as well as already mentioned before
So my assumption is that the libnfs implemention has some issues with the current NFS server from 5.10.11.
I will try to gather more information from the Kodi guys.
