FTR, I figured out how focal-proposed ended up enabled, with packages intalled from focal-proposed: the system had bionic-proposed enabled, but pinned to be low priority (so packages could be installed from proposed by manual override), at some point in the past. After upgrade to focal, the apt sources proposed line was updated to focal-proposed, but the pin (preferences.d) was not updated to focal-proposed being low priority (it still listed bionic-proposed as low priority, which was irrelevant after the upgrade to focal). This led to a number of packages being installed from focal-proposed, including the kernel images. I've explicitly downgraded a few of the less system critical ones (X11, update manager, etc), but will probably have to let the other 30-40 packages eventually get replaced by newer versions from newer Ubuntu Focal stable releases. Also FTR, the reports above (WARNING: CPU: 10 PID: 0 at net/core/stream.c:212 sk_stream_kill_queues+0xcf/0xe0) have continued overnight, but coming in bursts -- some hours had no reports, and other hours had 5-10 reports. So definitely feels like a race condition of some sort.
