i use 4 computers with Fedora 20 and Intel Core i7-4930K (6 cores - 12 threads). After update, two of them have problem with multithreading. I run 12 processes simultaneously using bash script, but half of threads stay at 0% of usage and half at 100%. Any help please??

UPDATE: Both problematic computers have Gigabyte X79-UD3. One of them had a kernel 3.17 backup and it works fine now. So maybe the problem is between this motherboard and kernel 3.19.
