Does this work for everyone else using 83xx? Odd... I don't have an 83xx board to test on unfortunately. Nothing jumps out as being obviously wrong in the assembly: ===== Pre-commit (works): fe000100 <_start>: fe000100: 3a a0 00 01 li r21,1 fe000104: 60 00 00 00 nop fe000108: 48 00 00 10 b fe000118 <boot_cold> fe00010c: 00 00 00 00 .long 0x0 fe000110 <_start_warm>: fe000110: 3a a0 00 02 li r21,2 fe000114: 48 00 00 0c b fe000120 <boot_warm> fe000118 <boot_cold>: fe000118: 3c 80 ff 40 lis r4,-192 fe00011c: 60 00 00 00 nop fe000120 <boot_warm>: fe000120: 7c a0 00 a6 mfmsr r5 fe000124: 48 00 00 05 bl fe000128 <boot_warm+0x8> fe000128: 7c e8 02 a6 mflr r7 ===== Post-commit (doesn't work): fe000100 <_start>: fe000100: 3c 80 ff 40 lis r4,-192 fe000104: 60 00 00 00 nop fe000108: 7c a0 00 a6 mfmsr r5 fe00010c: 48 00 00 05 bl fe000110 <_start+0x10> fe000110: 7c e8 02 a6 mflr r7 It'll be interesting to hear if the change affects other boards in the same way.
