To some degree this question is hypothetic because generally the cp0 count/compare timer will be the highest rated counter. But even if so, the basic solution is the same - just ignore the interrupt whenever it happens to be triggered. Or if it isn't shared with an active performance counter interrupt, you could even disable_irq() it. Ralf
