You can see that mempool_free is passing a NULL pointer to kmem_cache_free() which doesn't handle it properly. The NULL pointer comes from bio_free() where ->bi_io_vec is NULL because nr_iovecs passed to bio_alloc_bioset() was zero. The question is, why is nr_pages zero in scsi_req_map_sg()?
Note that the following patch I posted only addresses the part where slab is clearly failing here: http://lkml.org/lkml/2007/3/19/42 So, while it should fix the oops, there might be a bug lurking in the SCSI or block layer still. - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
