--- Comment #2 from sdh <sh.siddhartha at gmail.com> --- Booting with 3.12 kernel gives no such error. Using 3.13, booting from the Arch install iso gives the above errors. The only difference with radeon.dpm=0 is that the line "rv770_restrict_performance_levels_before_switch failed" disappears. I suppose this is related to the issue I faced with 3.10, where I could successfully boot using a install iso, but installing xorg + ati-dri and rebooting lead to a locked up black screen. In 3.13, it occurs in the initial booting itself. -- You are receiving this mail because: You are watching the assignee of the bug.
