desertoak, I just attached an URL to the upstream bug report I filed in the beginning of october. Since then Keith Packard have written a patch for this bug and Eric Anholt improved and merged that patch. The bug was in intel-agp.ko (a component inside the Linux kernel) and Eric's tree has been pulled into Daniel Airlie's DRM tree which is turn has been pulled by Linus Torvalds so it's very likely that this fix will be in the 2.6.28 kernel.
That said, this still means that G45-based motherboards might not boot on intrepid final unless someone from the ubuntu kernel team decides to cherry pick this particular patch (see below). I'm not sure that's going to happen though because we're beyond the "kernel freeze" in the intrepid schedule (at least I've e-mailed them about it). I suspect that the only change you need to make G45 work nicely is this one: http://git.kernel.org/?p=linux/kernel/git/anholt/drm-intel.git;a=blobdiff;f=drivers/char/agp/intel-agp.c;h=f1fe7490131468b40c5817e232442026d9f8ff0d;hp=016fdf0623a4ce7b5f849efc8ab099a2c5026497;hb=2052746fc8397130c120f0194a89938b0b62b6cb;hpb=b34c87315b1a2822111fc8ef744ef504f9be2f85 Applying this change is indeed sufficient to fix my machine. -- xorg hangs on startup (intel G45, compiz turned off) https://bugs.launchpad.net/bugs/273708 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
