I think we still want this message in, even if DEBUG is not defined. This code is conditionally compiled in for hardware debuger processing - and this message should really come out if this trap case occurs so the user has some idea that it just tripped. (The text of the message is not perfect, but that is a separate issue). Perhaps pr_alert() or pr_crit() would be better? Regards Greg
