https://bugs.freedesktop.org/show_bug.cgi?id=66963 was fixed but here comes new problem. When booting into X(KDE splash screen), it seemed to freeze(even after a cold reset), but I managed to switch to tty and get the dmesg. Xorg log is fine. In the end I have to shutdown. This situation seems to be more often than normal booting.
Are you saying this same problem happens even without dpm enabled?
