Subject:   BETA3 new message on rpi2 boot (just one boot?): dhclient[836]: send_packet: No buffer space available

[This appears to be something that does not repeat (often?) but I =
figured I'd mention it.]

I've not seen this send_packet report before the first BETA3 boot:

Trying shutdown -r now again to see if it repeated shows that it did =
not.

So far I do not see later problems in the first or later boots.
