Comment 43 for bug 1483343

@Joseph, i see similar error messages in your syslog.

Dell replace the motherboard of my notebook (Latitude 3450), and consequently processor Core i7--5500U @ 2.4GHz, Nvidia GeForce 830M 2GB are replaced.

After this fact, none of problems appeared again.

then, by inference, I think the problems occurred due to failure in the manufacturing process,

if you still want me to perform any test, please explain me step by step how to run it.

Sorry the noise.
