Too many of > us think they're pretty solid controllers. Well given that these controllers perform flawlessly with the snapshot kernels and the fact that they performed flawlessly when these systems were running NetBSD I can honestly say that I dont think the cabling or the termination is the issue. For clarity the cabling is the default cabling that comes with the AS200's and the termination is handled by the drive which is the only one on the chain. The relevant dmesg output is: ncr0: <ncr 53c810 fast10 scsi> irq 11 at device 6.0 on pci0 ncr0: interrupting at ISA irq 11 da0 at ncr0 bus 0 target 6 lun 0 da0: <QUANTUM FIREBALL ST3.2S 0F0C> Fixed Direct Access SCSI-2 device da0: 10.000MB/s transfers (10.000MHz, offset 8), Tagged Queueing Enabled da0: 3090MB (6328861 512 byte sectors: 255H 63S/T 393C) The error was: (da0:ncr0:0:6:0): extraneous data discarded.
