I've downgraded the following packages to 2.3.32: libdrm-radeon1 libdrm2 libdrm-intel1 libdrm-nouveau1a but the bug is still reproducible. So I guess it is also related to the following rendering packages, which have been updated two days before libdrm changes were introduced:
libegl1-mesa-drivers libgl1-mesa-dri libgl1-mesa-glx libglapi-mesa libegl-mesa libgles2-mesa libglu-mesa I forgot to mention that the program I use to reproduce the bug is a i386 binary, which depends on libqt4-opengl:i386. Will try to revert the mesa stuff and report back later. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1105389 Title: Arrandale GPU hangs occasionally after libdrm2 upgrade to 2.4.39-0ubuntu0.1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libdrm/+bug/1105389/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
