James & Arjan: Am I missing something here? It looks like fastboot: make scsi probes asynchronous has introduced a bug in the sd probing code. AFAICT, there is now nothing to prevent do_scan_async() from returning before sd_probe_async() has run. Doesn't this mean that there's nothing to prevent sd_remove() from being called and trying to unregister the disk _before_ sd_probe_async() has managed to register it?
