Contrary to a comment in the source, request->ack of a broadcast write request can be ACK_PENDING. Hence the existing check is insufficient. Debug dmesg before: AR spd 0 tl 00, ffc0 -> ffff, ack_pending , QW req, fffff0000234 = ffffffff AT spd 0 tl 00, ffff -> ffc0, ack_complete, W resp And the requesting node (linux1394) reports an unsolicited response. Debug dmesg after: AR spd 0 tl 00, ffc0 -> ffff, ack_pending , QW req, fffff0000234 = ffffffff Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
