This might as well be a behaviour of the driver that was tolerated before but is not anymore and thus might warrant a fix on our side ? While looking around the net for issues with pci_device_map_range, I've read about something similar in mga driver which was mapping 2 crtc to the same fb for clone mode. This worked for a time but then the driver needed to be fixed. This was circa 2010 iirc, so might be something different... <a href="https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-mga/+bug/292214/comments/8">https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-mga/+bug/292214/comments/8</a> > Perhaps, you can remove PCI_DEV_MAP_FLAG_WRITE_COMBINE to see if it helps. I've tried that, it didn't help.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
