It does have to be there. The ipl_handlers is supposed to be the a list
of all handlers of the same IPL.
Can you print what ih->ih_level and i are at this point ?
Maybe the value of ih, and the full list if ci->ci_isources[i]->ipl_handlers
would be usefull too.

Also, do you have a way to reproduce it ? I've never been able to reproduce
it myself.
