RE: Ping [7:61366]
I don't think it's an error. The first packet is probably lost while the router or switch is performing an arp request. That takes a second or two to come back, then the pings are successful. If you ping again (immediately after the first time when you loose one packet) you shouldn't see any dropped packets, unless there's another problem. That's because the router or switch is holding that arp entry. Wait a while and try again and you'll loose the first packet again, because the arp entry has aged out.

Re: Ping [7:61366]
The first PING is lost because the source system is performing an ARP request. The ARP information, once obtained, is cached (remembered) for a small amount of time. Successive Pings to the host should show all four replies.

RE: Ping [7:61366]
This isn't a Cisco issue, but the byproduct of a missing "new" entry in the ARP table. You may know the layer 3 address for this new interface and the router may know how to route it (i.e. this subnet exists off of this interface), but it does not yet have the layer 2 address needed for final delivery. So- your first series of Ping packets defaults to inverse ARP, and if properly configured, the new interface is known.
