2237,pcf50633 INT1 and INT3 flood logs with gadgetfs keyboard,lindi,openmoko-kernel,"Steps to reproduce:
1) connect freerunner to a PC and setup ssh access over wlan since g_ether can not be used during test
2) tar zxf testcase1.tar.gz
3) cd testcase1
4) make
5) sudo bash setup.sh
6) sudo ./usb

Expected results:
6) freerunner shows up as a new usb keyboard on the PC side

Actual results:
6) freerunner shows up as a new usb keyboard on the PC side but on the freerunner side it starts to flood logs with about 8 lines/second:

More info:
1) the keyboard gadget does not yet work reliably but that is not what this bug report is about :-)
2) I am using andy-tracking b8b36e5ec3db71d5
3) udevd seems to consume 5% cpu time constantly. strace shows
