I have this NFS server - P2B-DS (only 1 CPU) + extra 7890 + 13 ST118273LW (18G LVD) - panics once every several days with 'ufs_dirbad: bad dir' or 'fault on nofault entry'. I spend past 4 months swapping out every pieces of hardware with our other systems that would run for months. The only variable is that this is our 1st server using LVD (Ultra2) drives. You may have confirmed my suspicion that there was a problem with 7890 running Ultra2 drives. I tried upgrade the adaptec BIOS to v2.11 and increaed the PCI lateny setting to 128, but that did not solve the problem. I am at the point of giving up on the adaptec controller. I saw you mentioned that you had no problem with the NCR 35C875 chip. I was wondering which board manufacturer did you use . Do you know if they make a dual channel LVD (Ultra2-wide - we need the LVD bus because of the cable length) board using the NCR 35C875(6)? Or anyone has success with one?
