Test if it fixed crashes for you.
Well, I'm out of ideas 
In both logs I see that it is connected to a Marantz AVR.
Can you connect it directly to the TV, reboot, and post kodi.log?
I really have no idea why available modes are limited to 1080 for HDMI. Could be a driver or video bios table (VBT) issue. Try to update to the latest bios.
Also post kodi.log:
paste /storage/.kodi/temp/kodi.log
Has anyone any idea if there is a workaround to get deinterlacing work?
Disable "Allow using DRM PRIME decoder" in Player settings.
Is Mesa Intel Graphics (RKL GT1) a driver that should support 4K @ 60?
No, it is kernel i915 driver. Mesa is OpenGL/GLES stuff. Kernel 5.13 should properly support RKL, so I'm not sure what the issue is.
This latest image in post #751 crashes every 10-15 mins, and sometimes does a triple or quadruple crash loop.
No crashes at all on my box. Must be something specific to your NUC.
I tried this build on my NUC and it keeps rebooting every 5-10 mins. Gonna roll back.
Does it crash during playback?
EDID looks ok, no idea why Kodi is limiting to 1080. Try a clean install.
Run
paste /sys/class/drm/card0-HDMI-A-2/edid
and post the ix.io link here.
I compiled a new build with the following changes:
- AV1 VAAPI hardware decode (owners of TGL/RKL please test)
- added unmerged AV1 ffmpeg fixes:
github.com/intel-media-ci/ffmpeg/pull/403
github.com/intel-media-ci/ffmpeg/pull/412
LibreELEC-Generic.x86_64-10.0-devel-20210715034851-adbfe1e.img.gz
But the maximum resolution is only 1080
Maybe some sort of EDID issue? Is it connected directly to the TV?
Dump the EDID data post it here:
Run via ssh:
tail /sys/class/drm/*/status
Look for the "connected" device. If it is e.g. "card0-HDMI-A-1". run:
paste /sys/class/drm/card0-HDMI-A-1/edid
I compiled another Kodi 19 GBM build.
- media-driver 29d5f8f. hopefully fixes RKL issues ( audiosat please test)
- Linux 5.13.1
- Mesa 21.1.4
- HDR patches from lrusak

I'm using raspbian os
Maybe better post this on raspbian os forum?
it says for AMD, would this still work?
It will work.
Can SMP or others confirm this build is not capable of Dolby TrueHD and DTS-HD MA passthrough?
It should be capable. However, some people reported issues with passthrough audio on Gemini Lake.
The only downside is that 4k tops out at 30fps since it only supports HDMI 1.4
Not sure why that spec page says HDMI 1.4. Gemini Lake SoC has a built-in HDMI 2.0 controller. HDR is not possible with HDMI 1.4.
I am having issues playing certain MP4 files in this build.
Software decoding does not seem to work with DRM PRIME. Disable "Allow using DRM PRIME decoder" and it will play.
Build in post #698 is the latest and greatest. And probably the last one from me, at least until lrusak resume his work on HDR. No idea why it crashes for you, those builds are rock stable on my J4105 box.
