Ok, maybe I understood something wrong. I assumed that on newer
processors parity or ecc errors would be reported using the mce
mechanism. And I didn't find anything handling mce's. Therefore I
assumed that it would be possible that parity/ecc errors could happen
without beeing detected and logged. If these errors are still reported
using NMI then that is ok and an implemention using mce/mca is only
"nice to have" and not something that is required.
