[SOLVED] Firmware i915 error on OpenWrt boot

Installing and Using OpenWrt
1

I’m trying to install OpenWrt on an hp-PRODESK-600/8GB ram/240GB SSD . Installation is performed using
/releases / 23.05.2 / targets / x86 / 64 / generic-ext4-combined-efi.img.gz

After "burning" the image on an SSD drive and first boot, this error systematically occur 64 seconds after power ON.

Failed to load DMC firmware i915/skl_dmc_ver1_27.bin. Disabling runtime power management.
DMC firmware homepage: https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/i915

Still, OpenWrt seems to be running and I can access LuCI via the home network after some dhcp and network tweaking.
I found this web page concerning the i915 search key:
linux-firmware.git

The Question: How to correct this Firmware i915 error ?

I don't think that it is necessary to fix this, since it is related to the processor's internal GPU that is not being used in a headless use case anyway.

I have same error on x86 build. If you say its internal gpu problem which is useless anyway then good. Thanks

Unless you are running on a laptop with built in display. The downside is with power managment disabled the screen stays on all the time. To workaround I have to manually run setterm from the console on each boot and specify screen blank timeout. ( setterm doesn't work running at startup. )
