This was the most resent crash I have seen and I cannot see anything
which relates directly to MythTV or the USB connection to my hardware.
This could mean that the system does have an intermittent hardware fault
and that there is no software solution possible.

I will continue to gather diagnostics when I can in case there is some
strange condition I am hitting.  Hopefully I can find some new hardware
to setup and run the same USB TV Recorder from using the same version of
Ubuntu and MythTV.  If the fault does no occur on that in a month of
normal operation then I guess it would pretty much confirm if this is a
hardware fault in the host PC or not.  I will have to get hold of a
second recorder to confirm if it is the USB device that is creating an
issue but that can wait until after I have check that my host PC's
hardware is a likely culprit.

Title:
  Xorg freeze; system locks and accepts no input, keyboard lights go out
  when key is touched

Status in MythTV:
  New
Status in “nvidia-graphics-drivers-173” package in Ubuntu:
  New

Bug description:
  Binary package hint: xorg

  I have a rather old machine running a MythTV backend using a WinTV
  NOVA T USB2 (93000 Rev B8A2) and it seems that randomly the system
  will lock up completely.  I have done my best to work out if the
  freeze occurs when recording or performing some function of the
  mythtv-backend but based on the logs it seems that it can occur during
  a recording, during a database update or when there is no activity at
  all.

  I do have BOINC installed and running but disabling that so it does
  not run at startup didn't seem to stop the problem; as the freeze
  occurs randomly every few days I had to wait about a week but the
  system did lock up without BOINC running at all.  My next fiddle was
  to change the priority of the mythtvbackend process to be -3; this
  seemed to reduce the frequency of the freeze occurring but it may have
  been psychological as the occurance rate is so drawn out anyway.

  One thing which triggered a freeze was using the ubuntu-bug program,
  before the report that I am using to make this bug entry the system
  froze while ubuntu-bug was off collecting information about the
  problem.  Again the mythtvbackend was running so I cannot discount
  this just being coincidence.

  Another symptom, which may just be how the thing works, is that the
  NOVA T USB2 strays in "warm" mode during the crash and if I use the
  PC's reset button to restart the system.  When the system comes up
  like this the NOVA T is unresponsive and the red light on the from of
  it remains lit.  If I power down the machine or pull the USB cord out
  from the NOVA T then plug it back in after several seconds while the
  bios boot splash screen is going then the red LED extinguishes and the
  device works fine once Ubuntu has booted.

  This is all a little scattered and probably unhelpful but I have tried
  to hunt down answers to this problem myself and have run out of ideas
  what to do next.  Please do let me know if there are any further
  diagnostics that may be helpful.
