AGP Broke My Software Suspend

18 March 2004

It automatically loaded intel-agp.ko, which I never before loaded. This module caused a mysterious failure of swsusp. I'd end up in a resume-reboot loop. Once I added the module to the /etc/hotplug/blacklist, suspend continued functioning.

I had explored all sorts of possibilities trying to fix this thing:

In the end, it was this swsusp-devel message which clued me into the fix.
