Which interface connects to the Extreme switch? Can you try hard coding Speed/duplex on both sides? Also configure the following under the interfaces since you are not trunking
3750-B(config-if)#switchport mode access
3750-B(config-if)#switchport nonegotiate

Can you provide more details such as what IOS you are running on the 3750, the config and sh interface for the interface in question.
What model of extreme switch is it and what is the interface on it configured as?
