Afew other things:
A few other thoughts:
can you ping 224.0.0.5 hand have the upstream router reply through this
interface? Can you do the same for the upstream?
You are also missing information on your ospf packets, no length, no mtu - Try
shutting and no shutting the sub interface and see if that clears the problem..
Example on a debug ip os adj:
Jun 9 16:23:15.124 edt: OSPF: Rcv DBD from xxxx on FastEthernet0/0 seq 0x515
opt 0x8 flag 0x2 len 1472 mtu 1500 state EXCHANGE
Your debug...
