Can you check early_setup disassembly, see if r13 is assigned (it should be in two spots) and if it's clobbered by the compiler somewhere ? Also, you may want to try adding --ffixed-r13 to the CFLAGS in the makefile and let us know if it makes a difference... r13 is marked reserved by the ABI but segher seems to imply that gcc may decide to ues it anyway (ouch !)
