Weird errors from nouveau in dmesg

Lately I have noticed some weird errors in my dmesg from nouveau

Oddly it only happens when I try connecting a usb drive to my system, or at least it seams this way, I don't know why because the graphics driver should have nothing to do with the USB controller or so one would think.  I don't see anything in the Xorg log related to this error just within the kernel log.  Anyone else getting these errors?
