Is this really a reliable indicator of a problem? I'm also on Xfinity, and see the same thing - 3 out of 4 upstream bonded channels are in the "not locked" state according to my modem. They've been that way ever since I moved here.
However, I receive the full upstream bandwidth that Xfinity allocates for my plan (a pathetic 20 Mbps), and it has been extremely reliable, no outages. Since it looked like this from day 1, I made the assumption that Xfinity only uses one of the channels since the bandwidth they provide is so low. The power levels and SNRs for all locked channels (up and down) are green across the board.

Apparently it was a problem (according to a tech I spoke with over chat) because having a single connection meant that any interruption in that single channel meant the entire connection goes down. Depending on DOCSIS version that channel does support the full bandwidth. My upstream was generally around 10Mbps, which worked fine for nearly everything we did, but when things were bad, it'd drop to 1-2kbps or lower.
