I left my MythTV system running with my main account logged into TTY4
and have had serveral crasahes which produced out; there have also been
two or three crashes that did not produce any output but still locked up
the system.
This trace looks like it is communicating with the recorder I have
hocked up to the system via USB; I guess this means that my USB
controller, connection or recorder could be faulty or that some spurious
hardware fault occurs while the comms are running. It could also mean
that the firmware for the recorder is wrong, poorly configured or not
handling an event well.

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.
