On a side note and FYI, it's a recent bug, until at least Linux 3.15.2-2 (and since 2 years of use of this laptop) I had this kind of message: Aug 15 10:49:52 azerty kernel: nouveau E[ DEVICE][0000:01:00.0] unknown chipset, 0xffffffff Aug 15 10:49:52 azerty kernel: nouveau E[ DRM] failed to create 0x80000080, -22 Aug 15 10:49:52 azerty kernel: nouveau: probe of 0000:01:00.0 failed with error -22 Regards

You appear to be using bumblebee. Can you reproduce your issues without it? (Bumblebee is unnecessary starting with kernel 3.12 or so -- nouveau will auto-suspend the card when it's not in use.)
Ok, thanks, it makes sens ! I'm disabling it and will tell you if it happens again (or not)
No response to retest request without bumblebee. Marking invalid.
