Some USB problems - I think.
I have a USB Harddrive, 3G modem connected on musb bus and camera using omap3isp.
I am using a board heavily based on the BeagleBoard.
I am using 3.2 kernel from Robert Nelson repo.
It throws this error and seems to recover:

Then a bit later this error that causes a kernel panic and reboot.
Anyone have any idea as to where I might start to solve this problem? It has me really stumped!
