Are you powering the board via the USB OTG port? If you are there are two issues.

1) There is not enough power to power the board form the OTG port because of the onboard USB hub. You will need to use a double ended USB connector or a DC power supply. 2) If you have the OTG cable plugged in you will get a kernel panic no matter how you have the board power. There is an issue with the validation image supporting the OTG port. It will result in a kernel panic.

This is my first discussion. I received my three beagleboard xm modules and all 3 exhibit a kernel panic upon loading either the user image or the verification image. Below is the uboot version, angstrom version, and oops printout of the event. How can I fix this problem?

Thanks.
