Hi,
if the powernow-k8 module is loaded my Athlon BE-2350 dual-core machine
hangs at startup. 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.
[1] rtirq status for 3.18.9-rt5
[2] rtirq status for an older kernel
Regards,
Ralf
