Hello, We have a very strange SCSI problem running a Tekram dc3902ub (see http://www.tekram.com/hot_products.asp?Product=DC-390U2_Series ) with a Soyo P4Y Fire Dragon Mainboard (see http://www.soyousa.com/products/proddesc.php?id=3 ). The board is used for a file server: 8 large IDE disks connected to the onboard IDE channels realize the storage, the OS (FreeBSD 4.6 Release) is booted from SCSI Disk via PCI card Tekram (Symbios 895) controller. The SCSI disk is the only device on the SCSI bus. As soon as we access the SCSI disk we get SCSI errors we don't understand. What these messages make so strange: 1. If you move the Tekram, SCSI cable, SCSI disk, terminator "en bloc" to a different board (Asus P3B for example), the SCSI system works without problem. 2. We have exchanged really any component at the Soyo System (cable, power, cpu, board, RAM, ...) without any effect. 3. If we exchange the SCSI system at the Soyo system an put in a LSI logic Symbios 875 card with a Quantum 1GB Fireball insead we also get messages like shown below. 4. If we install a Generic Kernel with option options SYM_SETUP_PCI_PARITY=0 we still get error messages when accessing the SCSI disk 5. We have one system up and running with Soyo Fire Dragon and Tekram DC390u2b which works 24x7 for weeks without any problem with the SCSI components. 6. We are also unable to install other OS to SCSI disk. All installers (Win2K, Suse Linux 8.0, FreeBSD 4.5R, FreeBSD 4.6R) sooner or later fail with strange errors. FreeBSD gives the most detailed error messages of all of them. 7. Both BIOS's are up to date: Soyo: 2aa2, Symbios: 3.23 We are in contact with Soyo support team and want to give them a hint about what we think is going wrong. For us it looks like a problem between Soyo P4i Fire Dragon and Symbios based SCSI controllers. The SCSI error messages we get are not very "self explanatory" so I ask this list in the hope of an answer. If someone can help, please see my question in this context: What does the messages below mean for the motherboard, if I know _this_ Tekram controller, _this_ SCSI cable, _this_ terminator, and _this_ harddisk work in other mainboards without problems. What can I tell the Soyo support team? Syslog messages: Note: These messages are from a 4.5R network boot via xl0. This was done to fetch the messages elecronically and not manually (We are unable to boot from SCSI disk!). The DISKLESS_45 is a generic 4.5R kernel with additions for network boot. The scsi errors at the end are very similar for a 4.6R floppy/CDROM boot. ---------------------------- snip --------------------------- Copyright (c) 1992-2002 The FreeBSD Project.
