Well, the NCR driver isn't perfect (is anything), but I don't think the above is right ! High load makes problems show up, which existed before, but just were never triggered. The most recent such case I remember was caused by an old chip set (Saturn I), which failed within seconds under high load, if PCI optimizations are enabled. There is nothing you can do about this, it will affect any bus-master card. (Well, the NCR does fetch its microcode from system RAM itself, this makes it a little more sensitive to such problems) If you observe the NCR fail under high load, then please let me know and I will try to help. This is not its common behaviour at all!
