@Kevin su Armbian uses one kernel config for both server and desktop images. You could compile your own server image and enable this option. I can help you with build errors. SBCs often have relatively weak single-core performance compared to x86 servers. Full preemption prevents a single long-running kernel task from causing noticeable "stutter" in network responses or shell interaction.

I am currently on the community Odroid M2 CURRENT (6.18) (not edge 6.19) rolling release. Does this differ significantly enough from the images provided here: https://fi.mirror.armbian.de/incoming/igorpecovnik/ that I should download afresh and re-install before submitting any test results? Reporting! Where? (Every other section 1 - 7 had a necessary link) Much appreciated in advance. Willing to help or donate a M2 board if necessary.

@Nick A I agree with your point — for modern SBCs, the difference is probably not that significant, and it’s more of a psychological feeling. However, it would be even better if the new version could switch to CONFIG_PREEMPT_VOLUNTARY.
