Hi Here I'm submitting a patch for this bug. Mikulas From: Mikulas Patocka <mpatocka@xxxxxxxxxx> If blk_alloc_disk fails, the variable md->disk is set to an error value. cleanup_mapped_device will see that md->disk is non-NULL and it will attempt to access it, causing a crash on this statement "md->disk->private_data = NULL;".
