I've had this issue at random ever since earlier MikG versions, and im on 2.55 now and had it reboot/loop just yday as i was sending a text. I'm overclocked to 1152 on charge, 1113 most other times, and it happens regardless just at random. Usually only once every now and then, not very often at all, but a battery pull will bring it back up correctly. I always do a complete wipe process prior to upgrading ROMs, and its done it on nearly all Mik ROMs I've used, regardless of which SetCPU profile is being used. Could be a rogue app somewhere though as i always backup/reinstall the same apps regardless of ROM.
