It's probably a different issue then. Mine and many other's battery drain was related to excessive contact sync happening over and over again... It's easy to check though, just kill goproviders process on the phone and see if this improves your battery life.Hmm I thought your "solution" was a different custom ROM? Even if I sync an account with few (10) contacts it's the same issue for me...
dlog_system only shows Power Manager messages all day e.g.
06-04 13:05:36.359 303 303 I POWER_MANAGER: core.c: default_trans(1381) > S_LCDOFF -> S_SLEEP : check fail
BTW, did you experience the high drain when you were on the stock (non-rooted) Gear 2 ROM?
