Does it hang the entire system as soon as you load the driver, or only when you start X or something like that?
Hangs on driver load.
As for debugging, you can try disabling rv6xx_dpm_set_power_state() by returning early (see the patch below).
This doesn't work.. actually it seems to fail a bit faster now.. previously it would display kernel messages for a bit, not it goes off after extracting the kernel.
I tried exiting early out of a few other functions like rv6xx_dpm_init, but haven't had any better results. I put a printk statement in _init, which never got printed.. Could we never make it there? I couldn't find anything that comes before _init...
