Hanging on power management

Recommended Posts


I am having a problem booting the Niresh installer on my Lenovo G505s (59406417).


Here are its specifications:


Processor: Quad-Core AMD A10-5750M.


Motherboard Chipset: AMD K15 IMC


BIOS Version: 2.05, dated December 12th, 2013.


Network Cards:


       Wireless: Qualcomm Atheros AR9565

       Ethernet: Qualcomm Atheros AR8172/8176/8178 PCI-E Fast Ethernet Controller



Graphics: Dual Graphics - Integrated Radeon HD 8650G + Dedicated Radeon HD 8570M


Audio: Dolby Digital Audio (I couldn't find much info, sorry)


Memory: 6GB



I used these boot flags: amd -v -x.


While booting, Niresh abruptly stopped loading and hung on "power management may be incomplete or unsupported".




A few moments later, I saw a black mouse (a rainbow-colored wheel sometimes) and a reboot message:




How do I fix this?

I have read of others successfully installing Niresh on this same hardware... Why must I have all the problems...
