LE13 on Radxa ROCK 5B+

**chewitt** · July 26, 2026 at 6:47 AM

Kernel drivers have interdependencies and probe order isn't guaranteed so it's quite normal to see "fail" or "timeout" or "deferred" on first probe until dependencies are resolved and then probe succeeds (often silently or with low noise) later in the sequence. So is there an actual problem?

Only is not wakeup of this radxa from suspend after push power button, but is longtime issue.

Also i found h264 videos with aac audio, which runt freezing on start of playing with broken decoding. Here is one of them:

Device is booting and going at nvme with spi 2.0 from armbian. Only new information, maybe is everyday for rockchips.

If is enabled drm prime then is netflix video not played. Tested also at last build from 12. august 2026.

Playing local h264 was solved with change direct to plane to setting of EGL. But for playing Netlix i have turn off whole DRM Prime.

atirage21 · August 21, 2026 at 3:33 AM

With h264 in neflix are video not playing if is activated DRM Prime, If are av1 videos, then is playing with green artefacts.

In code "error" denotes a code path ending. In some cases that it represents a fatal problem. In others it represents nothing more than reaching the end of a branch in some form of logic or decision tree. In this case the content is not interlaced hence opening the deinterlace filter (correctly) errors and playback continues.

Please repeat tests on the current dev image from my test share. I have little interest in current Rockchip nightlies as they use older kernel drivers and ffmpeg, etc.

atirage21 · August 21, 2026 at 3:52 PM

OK, but there firstly i tested only as fresh install,... and i see big issue with turning off, which is freezing at black screen with title of build. Only after succesfully solution of turning off i will going to reinstall nightly build to development build.

If i changed direct to plane to egl, again is going with drm_prime also ...same behaviour as at LE13.

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:

Failed to create device link (0x180) with supplier 1-0042 for power-domain@8 (I2C FAN53555 regulator)
Failed to create device link (0x180) with supplier spi2.0 for power-domain@12 (Main SPI PMIC)

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.

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.

To be crystal clear, I have zero interest in bug reports against this kernel as it's about to be superseded with the 7.2 kernel as used in the images from my test shares. Dealing with temp things is a low priority to investigate, so repeatedly posting the same "still not working" post is just becoming annoying. I also haven't read the AI-slop 'guidance' posted, because Gemini is total garbage.
