Thank you for taking the time to report this bug and helping to make Ubuntu better. Reviewing your dmesg attachment in this bug report it seems that there is a problem with your hardware. I recommend performing a back up and then investigating the situation. Measures you might take include checking cable connections and using software tools to investigate the health of your hardware. In the event that is is not in fact an error with your hardware please set the bug's status back to New. Thanks and good luck!
