mako_hotplug: thanks to @showp-1984 tip the lcd callback is blocking so calling the void suspend/resume freqs that I had would just block the whole system and had to hard reset (this happened specifically if I called cpu_down(cpu_nr)). Scheduling works inside the notifier does work and the system doesn't get blocked anymore.
