t1_fatal_err() is invoked from the interrupt handler. The bad part is that it invokes (via t1_sge_stop()) del_timer_sync() and tasklet_kill(). Both functions must not be called from an interrupt because it is possible that it will wait for the completion of the timer/tasklet it just interrupted. In case of a fatal error, use t1_interrupts_disable() to disable all interrupt sources and then wake the interrupt thread with F_PL_INTR_SGE_ERR as pending flag. The threaded-interrupt will stop the card via t1_sge_stop() and not re-enable the interrupts again.
