Have seen the same problem here on my HP Compaq 8510w. While downloading updates (using the update manager) the filesystem suddenly locked up (switched to read-only mode). At that moment I had one virtual machine (VirtualBox) running as well, but I do not think think that's related to the problem.
After trying ubuntu for the first time, a friend of mine told me about this problem (exactly the same hardware). I told him it couldn't be Ubuntu's fault and finally decided to try myself. My system worked fine for at least a week before it crashed, and fsck was able to repair the filesystem. I have Ubuntu Jaunty amd64 running on a VMWare virtual machine and have not seen any problems there (yep.. the issue seems to be hardware- related...). I'll attach my lshw result as well. ** Attachment added: "lshw.txt" http://launchpadlibrarian.net/25943418/lshw.txt -- jaunty kernel 2.6.28-11 kernel update renders the system un-usable. https://bugs.launchpad.net/bugs/346691 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
