The kernel in /n/sources/contrib/miller/9/bcm supports multicore on the Raspberry Pi 2, but has an elusive "one last bug" which I suspect has to do with cache or page table coherency. The symptom is very infrequent memory corruption under heavy load, and the go test suite with *ncpu=4 occasionally triggers it.
