Just deleted over 100GB of logs from this bug. Fortunately, I caught it before my system became unbootable.
It seemingly only occurs after a power state change. I've noticed it when resuming from suspend and occasionally when plugging/unplugging power from my laptop. It doesn't seem to occur *every* time each one of those events occurs. I noticed the issue, because `uvcdynctrl` was using 100% CPU and causing the system to hang temporarily. I can confirm that `sudo killall -9 uvcdynctrl` will cause the logs to stop overflowing and the system to return to normal operating state. Previously, I was using a system reboot to resolve the issue temporarily. For now, I'll use the `kill` workaround to fix the system issues, and likely set up a cronjob to remove the offending log file. As others have mentioned, this seems like a high-priority bug. My machine is a Lenovo ThinkPad T410 (w/ webcam, obviously).
