If the Promise interrupt is being delivered on a different interrupt line than the one advertised (INTERRUPT_PIN), then dumping the state of the IOSAPIC should show which IRQ input is "high" and we can figure out where the disconnect is. But I'm skeptical that's really the issue. I suspect more the IDE command isn't being programmed properly into the Promise controller and thus it doesn't DMA correctly or for some other reason complete the command. ie it has no reason to interrupt. > The Promise Ultra100 TX2 controller is reported to work on PPC - not the > siimage one - so there is probably no difference between the PARISC and > PPC ports in this respect. ok grant > > Greetings, > Max
