the last thing done by the kernel is:
i2c i2c-0: i2c_outb: 0x34 A
i2c i2c-0: i2c_outb: 0x0c A
i2c i2c-0: i2c_outb: 0x5a A
meaning: enable power on, LINE IN, ADC, OSC, on the WM8731
so, after that, data is comming from the codec to the SSC and then is
handled by the DMA.
there must be something nasty on the DMA bus to hang everything like that...
