Running IOS XE 2.6.0(XNF) here, LACP works well.

One problem, though - ingress QoS is currently unsupported 
on the port-channel interfaces. While the recommended 
workaround would be to add them to member links, they don't 
work there either. Support should follow in coming releases 
(it's a real bummer!).

I'm also getting my SE to confirm on other limitations, 
e.g., support for only up to 4 members in the LAG.

My recommendation would be go for 2.6.0(XNF) as that offers 
a number of improvements in GEC (Gigabit EthernetChannel), 
as Cisco call it, e.g., better load sharing algorithms, 
e.t.c.

Hope this helps.

Cheers,

Mark.
