This error goes for a very long time. I have a hybrid graphics laptop (sandy bridge + radeon), and the only case radeon worked was fglrx. I'm using Gentoo and they have recently dropped any support for fglrx (mostly because AMD and Xorg had), so I tried fresh installation just to get some luck - and it failed exactly as before. Trivia:
- radeon and i915 as modules;
- power on;
- after login manager shows a pic, everything hangs deadly;
- using netconsole I was able to get dmesg error when everything freezes:
[ 470.521009] [drm] PCIE gen 2 link speeds already enabled
[ 470.522846] radeon 0000:01:00.0: No VRAM object for PCIE GART.
[ 470.523493] [drm:evergreen_resume [radeon]] *ERROR* evergreen startup failed on resume
I provide detailed system info shortly. Thanks!
