etherchannel question

I have two 3550 with 2 gigsatck gigastack connections modules connecting them which use firewaire at 1Gig

Can I use etherchannel?

2C-3550#show etherchannel 1 sum
Flags: D - down P - in port-channel
I - stand-alone s - suspended
R - Layer3 S - Layer2
u - unsuitable for bundling
U - port-channel in use
Group Port-channel Ports

1 Po1(SD) Gi0/1(u) Gi0/2(u)

you see the 'u' flag does that mean the interface can't be used this way ?
