--- Comment #199 from Bryan Quigley gquigs+bugs@gmail.com --- Latest kernel (daily build from the 12th) get's me a bit closer: Instead of booting to a video hang (monitor switch to powersave mode) it now hangs with the monitor on.
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.
It now hangs on startx. I can load the system in single user mode and then switch to dpm=1 fine. It's when starting X it hangs now.
What is relevant to try now?
