Incomplete dump, what it really means..
(davej@deviant:davej)$ ./a.out -b 2 -e 0xba -s 940040000000017a -a 0 Status: (186) Error IP valid Restart IP invalid. parsebank(2): 940040000000017a @ 0 External tag parity error Correctable ECC error Address in addr register valid Error enabled in control register Memory heirarchy error Request: Generic error Transaction type : Generic Memory/IO : I/O
Looks like the L2 cache ECC checking spotted something going wrong, and fixed it up. This can happen in cases where there is inadequate cooling, power, or overclocking (or in rare circumstances, flaky CPUs)
