An update: I've removed bcmwl and network-manager from the bug report because I no longer believe they're related. This same kernel error just popped up on an attempt to resume from suspend (I attached the log output to this comment; this seems to be more detailed than the other).
After resuming from suspend, the lock screen and the UI appeared normally, but the CPU average one minute load soared all the way up to 7.00 and I couldn't restart from the menu or really do anything. I forced shutdown with the power button before it could go any further. ** No longer affects: bcmwl (Ubuntu) ** No longer affects: network-manager (Ubuntu) ** Attachment added: "log2.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1124390/+attachment/3530562/+files/log2.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1124390 Title: Unable to handle kernel paging request at ffff8800fffffee0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1124390/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
