![]() The 3215 console irq handler used to schedule a tasklet. However the console irq handler also gets called from the infamous cio_tpi() function. Which in turn does something like local_bh_disable() [call console irq handler] _local_bh_enable() _local_bh_enable() prevents execution of softirqs, which is intended within cio_tpi(). However there might be a new softirq pending because irq handler scheduled a tasklet. In order to prevent this behaviour we just get rid of the tasklet. It's not doing much anyway.
