<div dir="ltr">Hello -<div><br></div><div>Anyone out there have any experience with the latest CCRMA RT kernel on Fedora 20 ? ie,</div><div><br></div><div> 3.12.5.-302.rt7.1.fc20.ccrma.x86_64+rt</div><div><br></div><div>
installed with</div><div><br></div><div> planetccrma-core-2013.12.19-1.fc20.ccrma.x86_64</div><div><br></div><div>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.</div>
<div><br></div><div>Not sure it's relevant, but it also throws kernel warnings with backtraces during boot-up, like these (from journalctl)</div><div><br></div><div>> kernel: WARNING: CPU: 2 PID: 858 at kernel/sched/core.c:2428 migrate_disable+0xed/0x100()</div>
<div><br></div><div>> kernel: WARNING: CPU: 2 PID: 858 at kernel/sched/core.c:2462 migrate_enable+0x17b/0x200()</div><div><br></div><div>> kernel: WARNING: CPU: 3 PID: 865 at kernel/sched/core.c:2428 migrate_disable+0xed/0x100()</div>
<div><br></div><div>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.</div><div><br></div><div>
I'd be happy to provide details, but first wanted to see if these are known issues...</div><div><br></div><div>Thanks!</div><div>Don</div></div>
