Has this device always needed a reset? The interesting bits of the log are probably the ones immediatelly preceding the decision to reset it. Two possibilities come to mind: something broke the reset logic (the device is clearly not working right after the reset) ... or something changed to make the device go bonkers _before_ the reset, which seems a bit more likely with my current lack-of-facts. (Especially if rc2 works and mm3 doesn't.)
