Ciao, Thorsten > with the device-tree of the Rock 5 Model B has been detected. All the stable kernels (6.7.y and 6.8.y) work on the Orange Pi 5, which has the Rockchip RK3588S SoC (same as the RK3588, but less I/O basically). So, being an owner of only two SBCs which use the RK3588* SoC, it appears that the Rock 5 Model B's DT is incorrect. > > I looked at the patch and tried several things, neither resulted in anything that would point me to the core issue.

Though I doubt that the later is the issue because if that were the issue, _someone_ with a Pine64 Pinebook Pro would've raised alarms. So far, this seems to be related to the `rk3588-rock-5b.dts` and possibly with the `rk3588s-rock-5a.dts` too. > > I would **love** to help but I'm afraid I device-trees are not something that I am at-all familiar with.
