I was working with comcast steve in the direct forum about my 6121 rebooting randomly. He said something about getting engineers involved and firmware.
Same here. Having issues with my SB6120 so I have the Aug 30th firmware on my modem. I wouldn't worry about it as it's not really doing anything for me... If I don't have bonded upstreams the modem can stay up for 4 or 5 days (or more). If I have bonded upstreams the modem is currently rebooting 4 times an hour. (Norm is about once every 3 hours)
