The PCIe lanes information seems to be read from the card itself (at least that's for RV515), look here: http://lxr.linux.no/#linux+v2.6.39/drivers/gpu/drm/radeon/r300.c#L553 While 1 is understandable (PCIe x1), 0 value is confusing and I can't tell if that'x x16 or not. Maybe one of the driver authorsa can provide some input. I've failed to locate any docs that contain information on the registers exposed on the PCI. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/564376 Title: Lucid - radeon kms causes iwl3945 to drop connection on youtube but not with mainline To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-driver-ati/+bug/564376/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
