When I manually shut down my Vista Ultimate x64, the screen says "Shutting Down" for about 10-15 minutes, then it gives me a BSOD reading "DRIVER_POWER_STATE_FAILURE." It dumped the kernel, and I perused it, looking for any clues that would help me at all. Apparently, my Marvell Yukon NIC driver was taking too long, so Vista has to initialize a STOP command and auto reboot. I updated to the latest drivers and I attached the debug from the kernel dump. Any help?
