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!
