This is a memory system error. "Soft" means corrected.  "mcr0" is
"memory controller 0" (there is only one controller on a 750).  The
"addr" field is a page address:  add 9 low-order 0 bits to get the byte
address of the beginning of the page; divide that by 1024*1024 (1
Mbyte) to determine which board is the culprit (for new-style 750s with
1 Mbyte boards).

In this case, 0x12ff << 9 is 0x25fe00; 1024*1024 is 0x100000; this
problem is in the third Mbyte (third board).  The "syn" entry can be
used to decode which chip has failed, but that decoding depends on who
made the memory board.  Consult the manufacturer's documentation.
