I forced it in the bios, no improvment. I also tried the drm-next-3.14 branch from Alex repository. Made it even worse: freeze on boot. Before i reached kdm and sometimes i saw the desktop. After applying the patch from https://bugzilla.kernel.org/show_bug.cgi?id=68571#c5 i am on the same behaviour like i was with stock kernel 3.13. I discovered that there is no kernel panic. I can get back to KDM with the SysRQ keys (Alt + Print + K). Maybe its because my card is slightly overclocked by the factory: http://msi.com/product/vga/R6870-Hawk.html (in compare with the reference card: 930Mhz vs 900Mhz). Something else i can do? -- You are receiving this mail because: You are watching the assignee of the bug.
