Just realised I plugged the wrong machine in. > Let me go find the right tacky white netbook. After a night of compiling, 915gm dies. Looking at the chipset spec, the reset mechanism should work just fine. My guess is that we are failing to disable the display engine and we get a chipset hang when it tries to access the disabled mmio block during the reset. Anyone still have a working 945gm? Meanwhile time to dig out an old kernel and check if we did get reset working then. -Chris _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
