Same problem here, system freezes after 2 - 10 min. Started after I added more RAM. Everything worked fine (no freezes past 12 months) this was when my system was running on 1 GB RAM (2x 512). I recently replaced the 2x512MB with 2x2GB modules. The system detects the RAM ok, but as everyone elses explaines above the system freezes.
I did tests on the new RAM but found no errors. Then I removed my Nvidia card - then the system worked just fine. My conclution ubuntu does not work well with 4GB ram together with Nvidia. My system: Ubuntu: 7.10 Gutsy (AMD64, x86_64) AMD X2 Dual core 4400+ 2x2GB RAM (DDR2) Nvidia 7300GS 256MB -- gutsy amd64 freeze crash lockup https://bugs.launchpad.net/bugs/157777 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
