I will test it again and analyze why. hi, ralf, in the latest master branch of linux-mips git repo, seems there is a need to select the SYS_SUPPORTS_HOTPLUG_CPU option in every uni-processor board, otherwise, the suspend/hibernation can not be used, because you have set: config ARCH_HIBERNATION_POSSIBLE def_bool y depends on SYS_SUPPORTS_HOTPLUG_CPU config ARCH_SUSPEND_POSSIBLE def_bool y depends on SYS_SUPPORTS_HOTPLUG_CPU so, the board-specific patch must be pushed by the maintainers of boards. and if the board support SMP, they must implement the mips-specific hotplug support, is this right? I have selected SYS_SUPPORTS_HOTPLUG_CPU in LEMOTE_FULONG and will push a relative patch later. Regards, Wu Zhangjin
