Sorry, Symbios used a different PCI chip ID for the J version of the 875, for reasons I do not really understand, but did not mention this in the 875 data book. The driver was fixed to accept both chip IDs (there is no difference between the two, as far as the NCR driver is concerned).

I'm using two NCR SCSI chips and a RealTek 8029 based Ethernet card in my system, too ... My guess is, that there is an IRQ conflict between PCI and ISA. Could verify, that none of the IRQs printed for the PCI cards is configured for one of your ISA cards, too. I do not know anything about your PCI BIOS (whether it dynamically assigns interrupts to PCI slots, for example), but assume some kind of configuration problem exists. > pci0:12: NCR/Symbios, device=0x008f, class=storage (scsi) int a irq 11 > [no driver assigned] Just replace the line reading: #define NCR_875_ID (0x000f1000ul) by: #define NCR_875_ID (0x008f1000ul) and rebuild your kernel. But this will make the driver ignore the non-J version of the 875. The drivers in 2.2-stable and -current have been fixed to accept both PCI IDs for quite some time, so you may want to upgrade, if you need one kernel that supports both at a time. Regards, STefan
