> I checked out the git trees, ran you script (had to comment out the 64 bit mesa stuff)
I'm glad you figured it out, since I created it for my own use and didn't take time to clean it up before posting it. Did your mesa get compiled with -fno-strict-aliasing? It needs that, maybe especially if you use a higher level of optimization than -O1. I'll attach a patch for configs/linux-dri-x86 (which again you'll have to clean up, because it changes lib_dir to lib32, for use on amd64 Ubuntu.) > i915 identifies itself as 20070209 version, according to dmesg. good. Check your other mesa versions with LIBGL_DEBUG=verbose MESA_VERBOSE=1 glxgears (and/or glxinfo) Leann> I'm flipping the status to Incomplete until we hear a report back from you regading stock Gutsy drm modules. Also marking Importance to "Medium". I have been unable to cause any lockups on Gutsy (kernel version sig Ubuntu 2.6.22-14.46-generic. I hadn't noticed that /proc file before :). I booted with just the Ubuntu version of the drm kernel modules, and ran stuff with LD_LIBRARY_PATH=/usr/lib LIBGL_DEBUG=verbose MESA_VERBOSE=1 nexuiz so I could verify that it was using /usr/lib/dri/i965_dri.so, not /usr/local/lib/dri. I checked with lsof that it's using the /usr/lib versions of all the libraries. Anyway, using stock Gutsy everything, I ran nexuiz and enabled all the eye candy (including HDR and dynamic lighting/shadows) at 1680x1050. timedemo demos/demo3 runs at < 3 fps, and sometimes down to 1 fps (on a g965, E6600, 4GB of DDR2-800). On edgy and feisty (with the previous version of Nexuiz, though), really low framerates would fairly consistently lock up my g965. I ran all five demos probably a couple times each. So I think it's fair to say that on desktop g965 hardware (Intel DG965WH motherboard), Gutsy no longer has problems. Or at least it's much better than Feisty. I'll try openarena, in case it reveals problems. Leann> However against the linux-source-2.6.20 package this is being marked as "Won't Fix" as it does not meet the criteria for a stable release update. I agree. I think I replied to this bug on the 2.6.20 page without thinking. The Debian BTS just has bug numbers... Although they probably do something special for kernel bugs, because they use package names with the kernel version in it, too. ** Attachment added: "tweak mesa configs by adding -fno-strict-aliasing" http://launchpadlibrarian.net/10170793/mesa-config.diff -- drm lockups on g965 hardware https://bugs.launchpad.net/bugs/104673 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
