Does this stay tuned mean, "Jay, hold off while I (Alexey) troubleshoot
this further."  Or does it mean, "Jay, you've not completely solved the
problem yet and you need to continue working on it."  If it's the
latter, can you please describe your setup and how you reproduce the
problem?  Is the box you have connected directly to the atl1 box used
as a netconsole?

Thanks for your help.
