Thank you for providing this information. I took a quick lock at the logs and the first thing that caught my attention were the additional devices provided by the docking station. Next, I say the following at the end of the kernel-docked.log:
[ 42.445360] retire_capture_urb: 36 callbacks suppressed [ 42.696115] delay: estimated 310, actual 1 [ 43.419428] delay: estimated 354, actual 1 [ 43.423747] delay: estimated 177, actual 0 [ 43.465214] delay: estimated 354, actual 1 ... This again suggests something related with a USB device. So, there are a couple of things we could try here. The first one would be, if if possible, to disconnect all the devices attached to the docking station. For example, the Wireless Headset, the USB Receiver and all the others. If this does actually solve the problem, we can try to go and start adding the devices one by one and see which one (or which combination) actually triggers the issue. If it is not possible to disconnect these devices (or if this does not solve the problem), another thing to try would be to compare the kernel modules loaded in both configurations (docked/un-docked). The list of kernel modules can be obtained through the command "lsmod". We could then try to blacklist the modules that are loaded only when the system is docked and try to find a possible buggy driver. Please post any additional information (success/failure) you can get from the tests suggested above. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/908335 Title: Kernel Hard Freezing Very Often To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/908335/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
