I've started testing with qos enabled and mt76 (2.4ghz driver) disabled, with my image, for now it seems that I don't see any RCU_sched warning anymore but I would need confirmation since for me it was always very random, and not easily reproducible.

I guess if there is none to test, I don't know if anything will get to trunk soon. Especially Since this hack is about removing patches impacting all MIPS images. But john should know better than I do.
