(ideally something around 10fps, for 1920x1080 frames) on the H96 max M9s.

 

that's really a good performance, congratulations

for comparison i do 3fps 320x240 on rk3566

Seems like I got some progress/regress with the board - I added some extra arguments in the armbianEnv.txt file - verbosity=7 and extraargs debug to try and see what the reason for the freeze might be and these three jobs were stuck, resulting in a kernel panic (end Kernel panic - not syncing: panic_On_set_idle_set) - systemd-udev-trigger.service/start, dev-ttyFIQ0.device/start and systemd-tmpfiles-setup-dev.service/start. Tried disabling the FIQ0 node in the dts (at least I think so), but the UART just stopped and it hanged again (the Armsom Sige 5 also has this in its dt). Managed to get a few times in initramfs, but it wans't helping me in the slightest. When adding init=/bin/bash, I could also avoid the hang, but it wasn't that productive.

Good news and bad news - I found the culprit for the kernel panic, but it's the GPU - once I blacklisted the panfrost module, it booted and completed the initial setup. The rknpu driver is v0.9.8, so it should be usable with the immich ML. Probably will try to investigate the GPU issue, but not anytime soon.
