Add > radeon.aspm=0 to your kernel command line in grub to disable aspm support. The issue still persists for me after using that patch and disabling aspm. I've attached a dmesg log taken after booting (to console, no X) using a 3.10 kernel, patched with the latest changes from the drm-fixes-3.11 branch (a01c34) and your aspm patch. And I've also attached the output from lspci since mine differs from OPs. I'm still kind of new to the whole patching thing (I'm a newb) so there's a chance that I may have done something wrong, but everything seemed like it went OK to me.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
