I think this is the same problem as
https://bugzilla.kernel.org/show_bug.cgi?id=23332

If you have more of the log, that would be useful, but I doubt you
do because I don't think the nx6325 has a serial port.  I do have
a sample of that system, so I'm hoping to learn something about it
today.

Thanks for the report!
