It seems to boot and run fine. If I try to log out of my GUI session, the monitors go into power save mode and never come back. I can SSH into the machine to reboot it.

I have attached the .config that goes with the information above. Any help in debugging would be appreciated. fasteoi irqs have been reworked in the I-pipe core patch (for linux 3.2). It would be nice if you could check whether 3.2 solves the issue you have. -- Gilles.
