The ideal scenario to help debugging this would be to get the kernel log during a system freeze through a serial console, but I guess your laptop does not have a serial port.
The other thing that *could* help finding the cause of this issue would be to compare the logs of a kernel that is known to freeze the system with your laptop docked and un-docked. So, you could: - Un-dock your laptop, boot, and get the kernel logs - Dock your laptop, boot and get the kernel logs The important thing here is to use the same kernel in both runs, and to pick a kernel that is known to trigger the issue. Would you be able to append these two kernel logs to this bug report? You can get the kernel logs by simply booting and running "dmesg > kernel.log" in a terminal. (This will create a file named "kernel.log", that you should append to the bug report). -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
