I just tried rev 211e47549b668c7cdd8658c0413a272f0d0495d4 (v2012.07-rc1)
for my PandaBoard.  Sadly, this is failing when I try to use the onboard
ethernet (EHCI USB based) controller:

Anyone else see this?  Ideas?

How do I map these addresses (PC=0xbff9acb0) to the ones in my
u-boot ELF image (so I can figure out what went wrong)?

Thanks
