To "lookup" an address in System.map, you actually look for symbol that
has the closest address that is lower or equal to the address you are
trying to match.
The interesting addresses are PC (c007dc80), LR (c007dc78) and
whatever is in the output of the "t" command in xmon if you have
working kbd input in there (that is with an ADB keyboard, not an
USB one)
Can you also check if the problem still happens without the USB
card in the machine ?
