Same error on my machine. I try to load the latest feisty release and I am contemplated with a black screen and a white cursor in the corner right after the ubuntu logo disappears.
My specs are as follows: Dell Optiplex GX260 Intel Pentium 4 1.8ghz 1GB Ram Ati Radeon 9200 -- [regression][rv280] black screen and console freeze when X starts - drm lockup https://launchpad.net/bugs/67487 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
