--- Comment #16 from Teofilis Martisius <Teofilis.Martisius at gmail.com> --- Hello, I can reproduce this problem on v3.15rc8 with power management enabled (radeon.runpm=1). So this hasn't been fixed in v3.15 yet. v3.15rc8 works OK with radeon.runpm=0 flag Sincerely, Teofilis Martisius -- You are receiving this mail because: You are watching the assignee of the bug.
