At least you norrowed down, that was the idea. I would suspect a new bug, so post to the radeon mailing list. Doing the git bisect first will make it easier for them so they'll be more willing to help. I would try booting without those radeon paremeters first. You could try the proprietary driver but the one in the portage tree will not build with a kernel >3.18.19 but if you search b.g.o there are patches to make it build. Or you could try my ebuild but I'm not sure that it will build either since I'm using 3.18.20 now: https://github.com/fernando-rodriguez/portage-overlay/tree/master/x11-drivers/ati-drivers -- Fernando Rodriguez
