Yes, seeing this too on 15.10 since around the first week of March, as
best I can tell, but irrespective of Suspend.
It looks like dhclient thinks/is told the new lease is 'depreferred' and
therefore quits, and the dhclient process is terminated, but the address
remains on the interface until the valid-lifetime expires.

Title:
Failed to renew DHCPv6 lease after suspend
Status in network-manager package in Ubuntu:
Confirmed
Bug description:
After fixing IPv6 address assignment (#1469346), IPv6 works fine until
sleep. On wake up ubuntu fails to renew its IPv6 lease:
Jan 13 10:47:47 ubuntu dhclient: PRC: Renewing lease on wlp3s0.
Jan 13 10:47:47 ubuntu dhclient: PRC: Rebinding lease on wlp3s0.
Jan 13 10:47:47 ubuntu dhclient: XMT: Rebind on wlp3s0, interval 9890ms.
Jan 13 10:47:47 ubuntu NetworkManager[796]: <info> (wlp3s0): DHCPv6 state
changed bound -> unknown
Jan 13 10:47:47 ubuntu dhclient: PRC: Address 2a02:xxxx:xxxx:xxxx::b44
depreferred.
Jan 13 10:47:47 ubuntu NetworkManager[796]: <info> (wlp3s0): DHCPv6 state
changed unknown -> expire
Jan 13 10:47:47 ubuntu NetworkManager[796]: <info> (wlp3s0): canceled DHCP
transaction, DHCP client pid 1170
Jan 13 10:47:47 ubuntu NetworkManager[796]: <info> (wlp3s0): DHCPv6 state
changed expire -> done
I'm not sure that it's solely NetworkManager issue (dhclient could
also be affected).
