mounting errors

Thanks for the tip Rob!  So it looks like my only resolution to this
problem is the dmesg silencing?  The only issue I see with that is
that perhaps something I need to see won't get shown.  Is this
something that can get brought to the attention of the kernel
developers?

Thanks,
Dave
