I am using a Overo WaterStorm Com and Chestnut43 board. I am receiving the following error:

I am using Android, with the Linux kernel version 2.6.32, a self powered usb hub and a RAlink usb wi-fi dongle. This issue didn't seem to be present when I was using an Overo Tide Com on the chestnut43 board or when I use the Waterstorm with a Tobi board. This error happens even without the wi-fi doggle attached and with two different USB hubs.
I have tried changing the cpu frequency 800, 600 and 300MHz and turned on Smart Reflex on VDD2 (compiled into my kernel and echo -n 1 > /sys/power/sr_vdd2_autocomp - Found a thread about beagleboards that were having a similar issue). I have tried with the 4.3" LG LCD screen disconnected from the Chestnut43 board. To be able to use the aforementioned cpu frequencies I edited the board-overo.c:
Does anyone have any information or experience with this issue? Is it hardware or software? Can it be fixed with either?
Any help is appreciated.
