OSMC with Kodi 19.1 Playback of large video files stuck

Hello,
I’m getting very similiar behaviour on Rpi4, which I’ve posted here:

but in my case remote NAS is mounted as NFS, which on my Rpi2 Kodi 18 works perfect.
I tried to play the same files on Rpi4 localy and via smb mount (the same NAS) and they played fine, so I’m guessing there may be something on network… but Ethernet is plugged via 1Gbps and WiFi works about 100Mbps - that should be more than enough.

What I did not mention in my previous post is kernel error in dmesg which happens at the moment when video freezes:

[nie wrz 5 20:55:59 2021] bcm2835_mmal_vchiq: timed out waiting for sync completion
[nie wrz 5 20:56:14 2021] bcm2835_mmal_vchiq: received invalid message context 5!

logs from kodi with debug states:

ERROR : ffmpeg[0x8052340X]: [h264_v4l2m2m] === poll unexpected TIMEOUT: events=0x147, cap buffers=18

Maybe this is somehow correlated to this thread…

Thanks, and best regards.
