Greetings,
Today I tried plugging in a second NCR SCSI controller card (Intel Plato P90
board). DOS boots up and the driver initializes both cards fine.
However, when I try Linux (1.2.4 and 1.2.8), the kernel finds both cards, says
something about 'reusing interrupt handler', and then test 1 fails due to a
lost interrupt. The system then hangs when trying to initialize the serial
ports.
If I pull the Interrupt jumper on the 2nd NCR at that time, the system
continues to boot and everything else works fine.
I have both NCRs set to INTA (which is routed to IRQ9). Both of them work fine
as long as I have only one card in the system.
If I set the second NCR to INTB, there is no hang during boot, but the error
(lost interrupt) is still there.
Another strange thing is that during initialization of the second NCR, Linux
tells me that it's using initiator ID 0 instead of 7 (on the first one).
Is a dual-NCR setup supposed to work, or is there still work to be done in the
driver?
cu
Michael
