Okay, I'm going batty over this one.  I've had my N2 for a bit now and love it. Recently I started upgrading my 1080 movies to 4k Atmos/TrueHD movies and they all fail with a hang or quit back to home screen at one point or another, usually within the first 10-30 minutes of playing. They will also hang on chapter skips/big skips.

Setup:

N2 4gig
Coreelec 9.2.2
eMMC Red Dot
Videos on external USB hard drives - tried 3 different ones

The typical log entry at point of failure is: CRenderManager::WaitForBuffer - timeout waiting for buffer

Short log snippit: https://paste.kodi.tv/dacekuvala.kodi

Complete log: https://paste.kodi.tv/evuqeroxon.kodi

I've tried different cache settings in Advancedsettings, default settings, just about any setting I can think of.

Any guidance would be greatly appreciated!

Have you tried connecting the drive to a different USB port?

Have you tried connecting the drive to a different USB port?

Yeah, all the ports and three different drives.

Do you have hardware acceleration enabled?

definitely points to sw decoding.

Yep, enabled and active.

I think you better report the problem here: https://discourse.coreelec.org/t/9-2-2-d.../10495/212
The devs can probably come up with what to test on your box.

Are the drives that you've tried 3.5" external drives with their own power supplies or 2.5" ones powered via the USB bus?
If the latter I've found many can be quite flakey across many devices, a powered USB hub may cure your problems if this is so.
If its the former its quite strange, my N2 works perfectly with 4k remuxes from directly attached drives or via NFS shares from my PC.

They are all powered; 2 Seagate and 1 WD.

I'm going to set up some of my hard drives into a software raid setup using Windows 10's Storage Spaces feature,
does anyone know if I use Windows ReFS file format and share the resulting spool via NFS that my N2's running coreELEC will read the files or should I stick to using NTFS?

ReFS vs NTFS doesn't matter.    It's the sharing protocol you choose to use that will determine compatibility.

I share my content from Windows hosts via CIFS/SMB (both ReFS & NTFS).   No issues accessing it from the N2.    I have only connected to remote NFS shares on linux based systems.   No issues there either.

Thanks @dwalme I'm now repurposing some older hdd's into a pool rather than buying a new large one

Wondering with the N2 can you install Ubuntu (18.04) and then use it to install Kodi? If so, is HD audio/video supported? I know you can install CoreELEC however I rather run Ubuntu... thanks!

Armbian have Bionic builds for the N2 with both the 5.4 mainline kernel and the Amlogic 4.9 kernel. I think hardware decoding is still not great on mainline so the 4.9 kernel is probably your best bet.

someone have test new CoreELEC 9.2.2 with  HDR10+ support on ISO/BDMV/mkv? ti's work well? 
thanks.

It's was working for some time in the nightlies before v9.2.2, so it should work fine in the stable release as well.
