I put the warning because a new pio task should not be queued while another one is pending. Therefore, either sff_pio_task_link is NULL [no task pending] or sff_pio_task_link is equal to the link of the task [assumed to be the task in progress]. I must have missed something and did not cleanup sff_pio_task_link properly in case of error... Gwendal.
