Thanks! The patch has the intended result on my Linux 3.8.8 kernel. All 4 CPU
cores are now being used and the cellminer hashrate went up from 42Mh/s to
62Mh/s (with 2 PPE and 16 SPE threads, just as before).
Could it be backported, especially to 3.8?
Again - thanks for your work and quick reply,
Dennis
