I tried with "nouveau.config=NvMSI=0" twice, everything worked fine. With "nouveau.noaccel=1" it also works.nForce 405 (C61) GPU. Try booting with the nouveau.config=NvMSI=0 kernel parameter. If that does not help, use nouveau.noaccel=1. Cheers, Sven
I also tried Fedora 21 Workstation Live today, which has the same problem. I opened a bug report there: https://bugzilla.redhat.com/show_bug.cgi?id=1188283
