Are you using an LCD cape? I have seen flickering similar to what you described with the 3.8 kernel when I forced a video resolution via the "video=" kernel command line option (in uEnv.txt in the boot partition) for the LCD3/4/7 CircuitCo capes and the 4DCAPE-43T/70T capes from 4D Systems. For those display capes, the resolution is pulled from the device tree overlay for the cape automatically, so you should not specify a video resolution. If you are using HDMI, you may not be getting the proper EDID resolution information from your display. In that case, the TILCDC driver will default to 1024x768, which your display (if it is an HDMI display) may not properly support. Either way, I have seen that refresh problem when the logical resolution that the TILCDC driver expects mismatches the physical resolution of your display device.
I have not seen that particular USB error before, but I also have not worked with the 3.10 kernel on the BBB. I've gone straight from 3.8 to 3.13/14.
