Strangely enough, I had exactly the opposite happen. With 2.1.5 and
the ed0 driver, adding an alias would often result in crashing the
system or it simply not working. i put them all on the loopback and
they worked fine from that point.

When I upgraded the system to 2.2-BETA (haven't gone to gamma yet),
I was able to put them back on the ed0 interface without experiencing
the same problems.

I did the same, with 2.2-BETA.
