So, by "reboot", you mean only an down/up of the interface.

Do you really have two interfaces (eth0 and ra0), or is that just a
mistake in the command you gave?

As Gabriel pointed out, your interface may lose it's IPv4 address when
bringing it down and then up.

If I remember correctly, ahcpd doesn't automatically re-add the address
when the interface goes down and up; are you using ahcpd, or assigning
addresses manually?
