Problems with tasklets and interrupts in Linux

Question

Let's assume that we have an interrupt handler and a tasklet in Linux. The tasklet is scheduled from this interrupt handler.

The problem occurs when the tasklet runs for longer time and interrupt occures when this tasklet is still running. This interferences causes several calltraces in logs.

Any other ideas?
