The resistor is a good idea, but I have seen 1 meg mentioned too.  It can be plugged in.

I am not really comfortable with just saying the board or the chip has a personality.
The truth is that everyone would like plug and play with infinite options, but oscillators and crytals from dozens of sources may require fine tuning [with a scope and/or frequency counter].  So they hang up.

Then, once you get an optimal set up for a particular frequency with similar component from same source, you might duplicate it sucessfully many times.  Also, there are a lot of 'sloppy' oscillator setups that will work and waste power, so working down from a high power FUSE setting to a lower power FUSE setting may hang.

I suspect that when you drive the properly tuned oscillator with less power, you will have less problems with the Brown Out as potential EMI reflected into the power lines is not driven as much.
