The Xorg 7.1 code looks quite different from the 7.0 code to me. Anyhow, a stable version of the Xorg 7.0 ati driver which includes the memory map fixes has been published upstream (version 6.5.8.1). I would really appreciate it if that could be made available for Ubuntu Dapper. Seriously, I will be willing to make a charitable donation a developer's beer fund. Can I also request that the importance of this bug be raised. This can lock up affected PCs (of which there are many in existence) frequently. I am using Kubuntu Dapper as a platform for KDE development and something in the latest Qt release seems to trigger this lockup very frequently. Switching to EXA accelerations helps - although EXA support seems to have many rough edges in the X.org 7.0, so much so that using it for day to day desktop work can be a little painful. -- system freeze when using ati radeon 7000 with xorg "ati" driver https://launchpad.net/bugs/16873 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
