Find out what function contains address 0xc00e3d68 by looking in the
System.map file. It's probably something board specific, as generic
Linux kernel code normally ends up at lower addresses. Then, try and
work out why it has made a call through a NULL function pointer. The
important information for you is NIP for the instruction address and LR
for the address the last subroutine call came from.
