I'm afraid this probably does reflect some sort of hardware problem. The MCE error code indicates that some kind of bus transaction failed. All the fields that indicate what type of transaction failed are indicating "generic," which is the catch-all for any type of error without and explicit code, so it's difficult to say specifically what kind of bus transaction is failing.
Marking invalid since this appears to be a hardware issue. If you find additional evidence to indicate there's a software problem you can reopen this bug. ** Changed in: linux (Ubuntu) Status: Incomplete => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/828533 Title: Kernel Panics Happening Randomly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/828533/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
