Steps to reproduce: 1.) Get a Lenovo T510 (latest BIOS installed) 2.) Don't use discrete graphics mode 3.) Install ubuntu 10.10 4.) Visit http://www.aclu.org/passengers-stories-recent-travel/ with Firefox 5.) Click around in the element <ul id="slidy"> (the graphics below "...slightly edited for clarity and length...") for some seconds to minutes. I could reproduce this bug three times in a row. When this bug occurs, Xorg freezes. You can still get a shell in via ssh for example. ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/696040 Title: kernel BUG at /build/buildd/linux-2.6.35/drivers/gpu/drm/i915/i915_gem.c:2108! -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
