Looks good to me, except for the two ohci_hcd and the nvidia threads. I
don't see those when you start rtirq but they are there when you query
rtirq's status. Weird. Same issue after a reboot? And this hdspm device,
is that an extension card (PCI, PCIe)? If so you might want to try
another slot because having it to share the same IRQ as your GPU isn't
ideal. And maybe you could post or pastebin your complete
/etc/default/rtirq file.

Best,

Jeremy
