I think I'm jumping the gun by blaming nouveau.  It does have it's quirks
and Gnome Shell seems to exacerbate things but here is what I noticed this
morning:

Problems seemed to happen as this message repeats more frequently:

kernel: [  346.862100] Disabling IRQ 16

Of course I have the trifecta of pain on IRQ 16:

IO-APIC-fasteoi   ehci_hcd:usb1, nouveau, firewire_ohci, snd_hda_intel

Then we get this a few times:

Mar 18 08:54:32 steve-lt2 rtkit-daemon[1613]: The canary thread is
apparently starving. Taking action.
Mar 18 08:54:32 steve-lt2 rtkit-daemon[1613]: Demoting known real-time
threads.
Mar 18 08:54:32 steve-lt2 rtkit-daemon[1613]: Successfully demoted thread
1838 of process 1838 (/usr/bin/pulseaudio).
Mar 18 08:54:32 steve-lt2 rtkit-daemon[1613]: Demoted 1 threads.

I'll paste the rest of the messages below.

Thanks,
Steve
