Please only inform me, if was dtb updated according to information of TTL due to next testing. Last dmesg log from build of 10. october 2026.
Thank you!

I see errors of rockchip-drm display-subsystem: [drm] *ERROR* POST_BUF_EMPTY irq err at vp0. If you know, please send me some commands, which can help to findinging of solution through e.g. TTL logs. Hre i uploaded DRM logs from LE 13 Nightly with kernel 6.19.
I uploaded booting and stoping UART TTL logs from Radxa rock 5b+ at testing build and also at LE13 nightly build. With kernel 7 is rarity of succes shut down, but was also recorded with logs.
UART TLL logs from LE 13 Nigthly build (is going from NVME) and Last testing build (going from SD card)
For RK3588 i dont see build at site: https://nightly.builds.lakka.tv/latest/

Rename or remove it and start over.
I identified, that vp9 at rk3588 (radxa rock 5b+) is ok, but only HLG way of HDR is problematic compare to good working HDR10 (tested at youtube online videos).
At only last builds is not going well inputstream.adaptive. I t was tested through slovak iptv addon: antik. I saw in changelog of LE13 that was many changes about addon inputstream.adaptive.
Edit: Solution was found. It must be reinstall cdm through inputstream helper. Now there is only longtime bug with antik addon with its archive support (it crash always after 6 minutes of watching, and in compare with archive is live stream watching without crashing - tested cca 2 hours).
Last two builds from 19. and 20. september have broken addons for e.g. gismeteo weather service and also libretro library.
Idea of retroarch is better but at LE13 is not going e.g. dkwnload and run some kernels.
Work developers is really the most important. But Gemini is interesting utility for creating own projects (i am not programator):
1. i found through gemini right components for my hobby project : DVD (with replacibility to blu-ray) player based on KODI
2. It create code for Arduino Mikro Pro for using of analog and IR buttons of old nonfunctional panasonic player.
3. It create links between Arduino and Kodi for right behaviour of Kodi at push of analog or original panasonic IR button. I uploaded files which i used in LE 13 and succesfully works (only for case of interest).
I am really happy that exist Gemini, Libreelec, and many opensource projects.
Next time i can update only logs with put nvme ssd apacer, because for me is small dificult a changing of configuration for logs. Therefore i wait for alternative turn on after suspending (button of desk is too deep in case).
Only with LE13 Nightly build is DVD going very well:
There is some ssh commands for identifing reasons ? And is possible enable wol in dtb tree for device Radxa Rock 5b+ ? This device dont have wakeup through cec hdmi and wakeup usb is not going. WoI would be good alternative for this. Thank you.

Dmesg log from last testing build at device Radxa Rock 5b+ with RK 3588 from 1. september (for sure was disconnected nvme Apacer and booted only from sd card)
https://paste.libreelec.tv/legginged-deegan.log
For example, playing of DVD is issue (not play, only error and system freezing). Compare to nightly build it need skip first scene, what is only temporary solution for going to dvd menu, but movie was again not started and whole system freezed (playing of audio cd is OK):

Also device have still turn off issue, because after turn off stayed at screen:
I wrote and sent logs from beta testing build which had turn off issue. Through AI i found some files which was updated last time for rockchips: https://github.com/rockchip-linux…se/RK3588_EN.md
In repo of libreelec i saw only 6y old rkbin: https://github.com/LibreELEC/rkbin-extra

Recommendations from AI gemini:
1. Core Settings Add-on (service.libreelec.settings)
Issue: Focus navigation failure on Control 1000 (window 13001) caused by a malformed JSONRPC type definition (Setting.Details.SettingList).
Action: Update Python API bindings in service.libreelec.settings to align with Kodi 22 RPC schema changes.
2. Missing XKB / Locale Definitions
Issue: XKB Compose table compilation fails due to missing en_US.UTF-8 locale definitions and an uncreated /storage/.config/xkb path.
Action: Bundle default locale files and pre-create the /storage/.config/xkb directory structure in the LibreELEC buildroot target image.
3. Audio Subsystem Initialization (ALSA/PulseAudio)
Issue: Log reports load failure for module-allow-passthrough, triggering an unexpected audio output fallback from the internal rk3588es8316 codec to hdmi0.
Action: Refactor default.pa / ALSA configuration for RK3588 targets to prevent loading unavailable passthrough modules on the ALSA layer.
4. Mainline Kernel Device Tree (DTS) — DMC / RAM Scaling
Issue: devfreq only exposes the GPU (fb000000.gpu). The scmi_clk_ddr node reports 0 Hz, leaving the Dynamic Memory Controller (DMC) without active DVFS scaling in kernel space.
Action: Mainline missing SCMI and DMC nodes along with proper clock bindings in the RK3588 kernel Device Tree.
5. SATA/ATAPI Optical Drive Handling (/dev/sr0)
Issue: dll_ioctl I/O error (code 5) occurs when reading sector VIDEO_TS.IFO, breaking libdvdread and forcing DVD media misdetection as an 18-track Audio CD.
Action: Patch the RK3588 PCIe-AHCI driver to ensure correct SCSI/ATAPI command execution and error handling for optical drives.
6. Kernel Hardening — eBPF Security Mitigation
Issue: Spectre v2 mitigation check reports Vulnerable: Unprivileged eBPF enabled.
Action: Set CONFIG_BPF_UNPRIV_DEFAULT_OFF=y in the LibreELEC RK3588 kernel defconfig to restrict unprivileged eBPF access.After 2 minutes playing of neflix at nightly build of LE13 with disabed drm prime are also issues.
According to AI Gemini is the reason for "turn -off issue" this error: rockchip-pm-domain ... Failed to create device link (0x180) with supplier 1-0042 which is connected with regulator fan53555
Recommendation for Kernel Maintainer from AI Gemini:
The boot logs highlight a probe ordering (race condition) issue on the Radxa Rock 5B+ (RK3588) running kernel 7.2.0. The rockchip-pm-domain driver attempts to establish device links before the corresponding PMIC suppliers are fully registered:
Suggested Mitigation: Adjust probe dependency ordering or ensure proper probe deferral within the rockchip-pm-domain driver and power controller subsystem. The power-domain controller must defer initialization until the required suppliers (spi2.0 and I2C devices) complete their registration, preventing missing device links that break system shutdown and suspend states.
And in case of problematic h264 local files (ff-mpeg4-drm_prime (SW)) with ativated drm prime and Direct to plane is not playing video:
