(Get the code!)
This may be related to this bug or it may not, but I will add it to the growing data-stream to try to help.
My system 12.04 ubuntu, then mythbuntu was showing exactly the same symptoms as this bug describes. It is a dual boot system with Win8 and ubuntu. Win8 was stable, ubuntu was not. Smart diagnostics were fine at first (hint of where we are going ;-) )
After 6 weeks of chasing the problem with multiple crashes, freezes, etc. I the smart diagnostics started coming up with some bad/suspect sectors. These were scattered around the disc in both the win8 and ubuntu partitions. They continued to grow until the drive failed specification--i.e. a bad drive.
I realize that without detailed diagnostics saved all through the process, this is total speculation, but perhaps as a hypothesis/place to look is in the handling of bad/failing sectors on the disc. Throughout the process, win8 never lost stability or data, but parts of the ubuntu would periodically crash due to read errors trying to read those nearly failed, intermittent sectors. I don't know enough (nearly nothing) about the back end of this, but that may be a difference here.
I replaced the drive 2 weeks ago and have had no further crashes or freezes (at least at this point).
