However, many lockups may still be caused by various AGP mode / fast write problems, even though some of the reports are not directly related to 67487. Things to do, and please eg. refer with a number always in relation to what you've tried, and tell what card you are using:
1. Some of the problems are fixed in Herd-4, so the first thing one should do is to make sure you still can hang the machine with Herd-4. Success reports plus card model are welcome. http://cdimage.ubuntu.com/releases/feisty/herd-4/ 2. Next, you could try the latest GIT version of xserver-xorg-video-ati, which has even more fixes to similar problems. I put compilation instructions (typo in the apt-get command though) near the end of bug 28925. 3. The upstream bug linked to this bug (fd.o 5986) links to Debian bug report that has a recently posted workaround that fixes the problems for some. Please try that on top of the current feisty driver, maybe that could be applied for feisty too: http://bugs.debian.org/cgi-bin/bugreport.cgi/radeon-rv280-cp-twopointlines.diff?bug=301531;msg=86;att=1 These would be good things to check on at least a) a 9100/9250 AGP card / machine, and also with some b) Radeon 7000/7200/7500 or c) early Radeon Mobility class machine if possible, just to get perhaps new information. No guarantees if any of the fixes fix these random hangs, but it'd be good to find out. So when we have either 1, 2 or 3 working for all of a, b and c, we have a lot of new information :) (the bug 67487 states that radeon 9500/9600 lockups should be fixed in herd-4 anyway) -- graphics lockups with radeon DRI https://launchpad.net/bugs/63503 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
