Hi, I test myself which says when CONFIG_CPU_IDLE=y, Lenovo ideapad S10-3 can not boot. The CPU is Atom N450, and I also find the report[2] that says intel_idle works fine with N450. I do not have much knowledge about intel_idle. is there any similar report that on some machine intel_idle halt the system or any suggestion for next step debug?
