  Make sure you're really building a Malta kernel of the correct 
endianess and CPU type.  It's easy to load a big-endian kernel on a 
little endian board when using srecord downloads.
  Try disassembling the code at 0x802e0024 to see if it makes sense:
YAMON> dis 0x802e0024

  You didn't say what CPU you were using.  It's possible that the 
kernel is really using an instruction (eg a cacheop) that is not 
supported by your CPU.
