MSI is indeed enabled in 325.15 Creating a test system (ubuntu 13.10) took a while my setup is: - apply a patch to NVIDIA drivers because Kernel 3.11 is used (via google) - disable modeset (kernel cmdline: nomodeset ) - blacklist vesafb, nouveau (modprobe.d entries and cmdline: rdblacklist=nouveau nouveau.blacklist=1 nouveau.modeset=0) - enable vga console (cmdline: video=vesa:off vga=normal ) - install nvidia custom driver (created by --apply-patch patch311.patch) - reboot two mmiotraces are attached</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
