not sure if that is what is configured on your 2924XL, but:
port group 1
--> switchport access vlan 22
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1,30-40,1002-1005
switchport mode trunk
no cdp enable
the interface cannot be trunk and access port at the same time, so take that line out (actually I think that the IOS would not let you type this in anyway).
There are a couple of things to keep in mind when configuring trunking on the 2900XL/3500XL switches, here is what the documentation says:
On a 4MB DRAM Catalyst 2900XL switch, trunking is only supported with the following trunking-capable modules:
2900XL and 3500XL switches do not support Dynamic Trunking Protocol (DTP). Thus, it is recommended that you use the nonegotiate option (for the switchport trunk command) on the other side of the trunk link This will prevent the XL switch from receiving DTP frames (from the peer) that it cannot proccess.
