Drivers that do not implement quiesce() may work depending what they do when going down. Drivers that implement quiesce() correctly are guaranteed to work. I have 4 drivers in my M1330 that do not implement quiesce() and I have to unload only one to be able to fast reboot. They are: agptarget hdaudio iwk (quiesce() is implemented on the driver included in builds 102) sdhost If I am using the nvidia 177.14.12 it is reported as not having quiesce() too. The only driver I need to unload for fast reboot to work is iwk. I was told the problem for certain types of GPU in the nvidia driver 177.80 were fixed for build 101. I am already using this driver. As well as the fix for '6767575 uhci_quiesce() should clear status bits' as I mentioned in the original email. The only drawback of using the nvidia driver 173.14.12 during fast reboot is that the screen does not drop to text mode, so that I cannot see the OS banner and messages when it is coming up. The logs show the reboot took 2 sec. So it is fair to say fast reboot worked.
