I have an Adaptec 2960UW SCSI controller in a Tyan II motherboard with 2 Pentium processors. I had been running this with the SMP kernel with RH Linux 6.2 but it has not worked since I upgraded to the 7.X RedHat versions. When the system is booting and doing the SCSI probe the requests timeout, apparently because the driver does not receive the interrupt. It works with a single processor kernel but I am trying to get the most out of my old 166 processors. Any pointers about how to use both cylinders again? (I have tried the SCSI adapter in multiple PCI slots. I also had an I-Will SCSI-3 adapter, thought it was faulty and reverted to the Adaptec with the same results.)
