also .....
i think you have said this ...but make sure that on the switches
TX on A - RX on B
RX on B - TX on A
i think you have done this ....
or
turn on portfast .......
make sure you have just standard trunking on ....if on side neg and one off
...could case probs...
i don`t think any of these could be causing the problems ....
try changing the cable also move the gbic to the other port ....and try
again....
but if you int is coming up .....it could be spanningtree or something along
those lines
