I think I have a similar problem after updating my Vostro 1500 to Hardy (5 days after LTS ended on Gutsy).
The problem for me goes about the same: 100% disk and CPU usage with no end in sight. GNOME is unresponsive, except for clock and gkrellm updates, and moving the mouse pointer. I can try to start firefox, or gnome-terminal, but they always die, and the programs I have running refuse to close. I eventually get impatient and power-cycle the machine, which sometimes leads to a black screen (maybe xorg didn't start properly). Booting in recovery mode seems to work, though one check comes back "[Failed]" and flies by too fast for me to see. What log would I find that in? After power-cycling a couple of times (wasn't patient enough to see if the deadlock ever ended) I stopped using GNOME and switched back over to fluxbox (my WM of choice). The problem hasn't occured under fluxbox yet, leading me to believe that the problem is related to whatever happens when you choose "Run Xclient Script" at the session menu. I was running top a few times that this happened, maybe Rob should try that, see what's eating the most CPU when this happens again. I saw dd, which could explain the disk usage, but it only had 50% or so of my CPU, and unfortunately I don't remember the others. There were three or four of them using the most cpu power, with at least two running at 40% to 50% Hope this helps, ~jdacronym -- Hardy Heron locks up https://bugs.launchpad.net/bugs/249123 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
