It means Dave sucks and hasn't done a good enough job on the parser. parsemce is really really unintuitive to use.
There's some bits missing from your dump. Usually, MCEs look like..
Sep 4 21:43:41 hamlet kernel: CPU 0: Machine Check Exception: 0000000000000004 Sep 4 21:43:41 hamlet kernel: Bank 1: f600200000000152 at 7600200000000152
All we have to go on in your example is the bank status code. (which is -s, not -e. -e would be the 00000000000000004 in the example above. [*])
So, without the missing bits, we have to fake it..
(davej@deviant:davej)$ ./a.out -b 1 -e 1 -s 9000000000000151 -a 0 Status: (1) Restart IP valid. parsebank(1): 9000000000000151 @ 0 External tag parity error Error enabled in control register Memory heirarchy error Request: Generic error Transaction type : Instruction Memory/IO : Reserved
Ignore the Status: line, thats decoded from the (faked) -e 1.
Any the wiser ? 8-) [*]

[*] See, unintuitive, evil and nasty. Given the time, I'd start over from scratch.
