Description angelfr83 2014-03-23 21:51:03 UTC

Hello,
I have tried several distros and whatever I do, I can't boot with any kernel of 3.13 or more.

With Fedora, I filled a bug report here (You will find more information there) : 
https://bugzilla.redhat.com/show_bug.cgi?id=1072929

I tried a *buntu distro, and I get exactly the same problem.

Using a koji kernel build on fedora I managed to boot on text mode.

Tell me whatever information you need.

Have a nice day.

Thanks.

Does appending radeon.runpm=0 to the kernel command line in grub fix the problem?  Any chance you could bisect?
