Typically under error conditions, it is possible for aac_command_thread() to miss the wakeup from kthread_stop() and go back to sleep, causing it to hang aac_shutdown. In the observed scenario, the adapter is not functioning correctly and so aac_fib_send() never completes (or time-outs depending on how it was called). Shortly after aac_command_thread() starts it performs aac_fib_send(SendHostTime) which hangs. When aac_probe_one /aac_get_adapter_info send time outs, kthread_stop is called which breaks the command thread out of it's hang. The code will still go back to sleep in schedule_timeout() without checking kthread_should_stop() so it causes aac_probe_one to hang until the schedule_timeout() which is 30 minutes. Fixed by: Adding another kthread_should_stop() before schedule_timeout() Cc: stable@vger.kernel.org Signed-off-by: Raghava Aditya Renukunta <RaghavaAditya.Renukunta@microsemi.com> Reviewed-by: Johannes Thumshirn <jthumshirn@suse.de> Signed-off-by: Martin K.
