An interesting observation is that your BSP engine refuses MMIO writes when coming back from sleep, but it was fine on original boot. We're probably not initializing something we should be... :( [The BSP engine in itself isn't that important -- it's for h264 decoding, but it's an unfortunate indicator.] And then you end up with a bunch of [ 5298.803245] nouveau E[ PFB][0000:02:00.0] trapped read at 0x0020ea1200 on channel 0x0000fc33 [compiz[2007]] PGRAPH/DISPATCH/M2M_IN reason: NULL_DMAOBJ Which eventually kill X as well.
