I should provide perhaps a little more background about nodemgr. It waits for events on the FireWire bus. If it detects physical removal of a node, it calls remove callbacks from IEEE 1394 protocol drivers such as sbp2. That's where sbp2_remove() kicks in. So it all happens in nodemgr's process context, although the hang occurs somewhere in the scsi mid or high level, or perhaps in the driver core when it is called from scsi. [...]
