After building the kernel with "CONFIG_X86_POWERNOW_K8 is not set" startup finishes. For older linux-rt versions I could unbind 2 USB ports sharing an IRQ with my sound card, by one and the same script, now it doesn't work anymore. The status of rtirq reports one IRQ with a "cryptic" name. I'm still using rtirq 20130402, not the current version 20150216, but the version of rtirq seems not to be the culprit.
