Hi all, I have a big problem with my Tyan Thunder K8S Pro S2882 dual-Opteron board and I wonder if you can help. I'm running FC3, kernel 2.6.10 smp. I've reduced my system to a boot disk attached to the on-board SCSI, and no other disks. If I plug extra Adaptec 39320 SCSI adapters into the PCI-X bus I get large numbers of assorted PCI errors logged (like PCI Interrupt Error), when I access the SCSI disk with commands like 'dd if=/dev/sda of=/dev/null bs=65536'. If I remove any one of the extra adapters, the problem reduces. If I remove any two of the extra adapters, the problem goes away. I've tried using the single-processor kernel version, and I've tried booting from a Knoppix 3.6 CD (2.4.27 i386 kernel) but the problem still occurs, although to a much less extent. The Tyan support FAQ indicates that a PCI-X interrupt routing problem was fixed at BIOS 2.03, and my BIOS version is 2.03. I've also tried disabling the Adaptec INIT13 in the non-boot adapters and the PCI-VGA interrupt on the Tyan BIOS, but the problem remains. I'm contacting my vendor and Tyan, but in the meantime any ideas anyone? Has anyone seen this before? Cheers, Terry.
