st: running xttest2 (Breusch-Pagan)

Hi statalist
I want to be able to test for heteroscedasticity (preferably Breusch-Pagan)
after running an instrumented regression on an unbalanced panel.
When I use xttest2 after ivreg2 I get the following error:
***********
Error: too few common observations across panel.
no observations
r(2000);
***********
Does anyone now how I can get around this error? Or maybe a command that
does work.
Some help would be greatly appreciated
