the kernel thinks that all events of type 0x48 (L1D_PEND_MISS) can only go
into one of the counters, and thus you can't have multiple at the same
time.
If this is a bug you'll need to report it to the perf_event developers.
I'd double check intel's documents to see what they actuall say about this
class of events on your processor.
