I remember that you had boot problems a while ago, together with a couple of other AMD cpu users. IIRC it just affected a few specific AMD cpus. AFAIK, you could not succesfully boot any kernel starting with with 3.12.6-rt9, and I have another report from another afflicted user saying that the boot problem was fixed by reverting: timers-do-not-raise-softirq-unconditionally.patch timer-Raise-softirq-if-there-s-irq_work.patch timer-rt-Always-raise-the-softirq-if-there-s-irq_wor.patch This might be significant, as these patches are in play again, at least on 3.18-rt. Try to revert those patches and see if the kernel can boot. -- Joakim -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
