Oh yeah, that's our "midwinter handwarmer" process in action. Nahh just playing lol.
Actually LEGO ROM and ThundeROM are very similar in architecture, almost identical leave the kernel. Are you sure it wasn't an application in the background running the CPU? What was your exact setup?
In my experimentation to narrow down the issues over the last couple of days, the only thing ive installed from the market is Hotspot Widget and SMS Backup/Restore. Running stock kernel with Two Point Two.
The problems I was having such as massive battery drain while tethered were attributed to having JIT & HW enabled. The system-wide lag I was getting in TR 1.6/1.6.2 has not showed up in Community, nROM, or LEGO so I don't know where that would have come from.
