The program streams data from the USRP (Universal Software Radio Peripheral) and calculates a transfer rate. It looks like the test completes and the program ooops as it is exiting.

Let me know if I can collect anything else. I am not much of a usb guy :(

What version of the kernel were you running?  On what hardware and
using which USB host controller driver?  Is the problem reproducible?

This is just a warning, not an oops. Nevertheless, it should not happen.

Doh, silly me for leaving out details ....

Beagle Board, OMAP3 based. Kernel is a fairly recent git + some patches. I can backtrack to an exact collection if necessary. I ran the test program several times and the system hangs when the program ends. I do not think I get the warning message every time though, the system does hang every time.
