Hi Jean, I remember finding an st module load/unload kref accounting bug a while ago: http://thread.gmane.org/gmane.linux.scsi/77539 I replied to the report with a hack-patch that grabbed an extra reference to avoid the crash. There was an attempt at fixing this up in the block layer [1] but that change was pulled when problems were found with that patch [2]. [1] https://lkml.org/lkml/2012/8/27/354 [2] https://lkml.org/lkml/2012/9/22/113 Maybe this is the same bug?
