Hello -

Anyone out there have any experience with the latest CCRMA RT kernel on
Fedora 20 ?  ie,


installed with


On my HP Elitebook 8540w (Intel i7 @ 2.67 GHz, 8 GiB RAM, nouveau nVidia
driver), it works fine - I tested quickly with jack and Ardour, using the
internal Intel HD sound card - but the computer freezes when I try to
suspend, requiring a hard power-off to reboot.  I'm able to suspend and
resume fine with the stock F20 kernel.

Not sure it's relevant, but it also throws kernel warnings with backtraces
during boot-up, like these (from journalctl)

> kernel: WARNING: CPU: 2 PID: 858 at kernel/sched/core.c:2428

> kernel: WARNING: CPU: 2 PID: 858 at kernel/sched/core.c:2462

> kernel: WARNING: CPU: 3 PID: 865 at kernel/sched/core.c:2428

some of which say the kernel is tainted (flags G W), while others say it
isn't.  I don't seem to see those issues when I look at previous boots
using the stock kernel.

I'd be happy to provide details, but first wanted to see if these are known
