just recently made the jump to v48 and getting random reboots now. never had it before. Got the speed/battery patch thing too. Will try and get rid and see what happens. If the problem goes away maybe that will help someone in diagnostics or something. Also noticed when looking around at what might be happening. It doesn't matter what I set the speed at, or change it too, it always seems to reset back to 750/500 when I look on QCPU. Never seen minimum at 500 until now. was always 250 and at occasional times 125. So even if I try to set to power kernel to 600 250 and either reboot myself or wait til it randoms (couple of hours sometimes) It always goes back to 750 500 when I look.
