Well ... I seem to have got parameter getting and setting working just about OK (modulo a few coupling issues). The fusion driver seems to have quite a big event subsystem. Is there an event that will report a device transfer agreement change? (without this it's a bit difficult to keep track of where the device and the fusion core are with negotiation) Thanks, James - : 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
