And I confess I tried modprobe amdgpu after a kdump, no success - kdump won't call shutdown handlers, so GPU will be in a "rogue" state... My question was about regular kexec because it's much simpler usually, we can do whatever we want there. My line of thought was: if I make it work in regular kexec with a simple framebuffer, I might be able to get it working on kdump heheh _______________________________________________ kexec mailing list kexec@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/kexec
