Could you retry suspend/resume with AGP compiled in but without the DRM (uninstall drm-kmod)? If having agp in the kernel is causing suspend/resume problems, then maybe it will be fixed by re-doing the initialization of the AGP after resume like linux does. Once I played with that on my laptop, which also has suspend/resume issues. It looked like AGP was still configured right after resume but before the machine hung, so I didn't try reconfiguring. Now I think I probably should have. -- Eric Anholt eta@lclark.edu http://people.freebsd.org/~anholt/ anholt@FreeBSD.org
