I'm guessing your pcie bridge does not have a large enough aperture for the frame buffer BAR. It's generally 256MB. The driver can't work without access to vram. Please attach your full dmesg output.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
