I was running a batch process on my computer (converting file formats and rendering pngs) when the following happened: 1. The mouse started lagging 2. Panels, menus, workspace switching, etc. stopped working 3. I logged in to a text terminal (Ctrl-Alt-F1) and killed the batch script and the renderer subprocess 4. Graphical environment started working a little better, and I clicked "stop" all of firefox's "unresponsive script" dialogs that popped up 5. Graphical environment hung again, so I killed unity-????-server from the text terminal 6. The unity menus rebooted, hard drive access stopped for a while, and everything seemed more or less fine 7. The computer hung completely, and needed a hard reboot 8. I checked the kernel log and it looked nasty.
Some other notes (don't know if they matter): The wireless switch was OFF, and the computer was connected to ethernet The laptop was plugged into power and charging when I began the batch process, and plugged in and fully charged after the reboot. An older version of the batch script running overnight may have frozen at the exact same file. (All I know is that the computer hung, and it stopped at around the same place) In short: I can count on having to reboot Ubuntu once a day, at the most inconvenient moment imaginable. Can anyone tell me what's going on? Is this an Ubuntu bug? A hardware problem? Something else? ** Attachment added: "Kernel log from when the computer was running with intensive lag and constant hard drive usage." https://bugs.launchpad.net/ubuntu/+source/linux/+bug/835857/+attachment/2340777/+files/kern.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/835857 Title: Lifebook T901: system crashes, hangs, etc at frequent intervals To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/835857/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
