I managed to get the first error messages: Attempting to Queue an Abort message: CDB 0x3c 0xa 0x0 0x0 0x0 0x0 0x0 0xfc 0x0 scsi0: hwerrint, Discard Timer has timed out scsi0: hwerrint, Illegal Opcode in sequencer program then it gets to the messages I included in my previous message. > > but here is the transcript of what I can > > see: > > > > scsi0: hwerrint, Sequencer Parity Error > > scsi0: hwerrint, Data-path Parity Error > > scsi0: hwerrint, Scratch or SCB Memory Parity Error > > scsi0: hwerrint, CIOBUS Parity Error > > > That's a pretty comprehensive sequence of parity errors.

I also don't think so because I get this same exact error if I try this SCSI board on three different motherboard models BUT there is one fourth model where I don't get these errors. Some info on the "working motherboard": # lspci 00:00.0 RAM memory: nVidia Corporation MCP61 Memory Controller (rev a1) 00:01.0 ISA bridge: nVidia Corporation MCP61 LPC Bridge (rev a2) 00:01.1 SMBus: nVidia Corporation MCP61 SMBus (rev a2) 00:01.2 RAM memory: nVidia Corporation MCP61 Memory Controller (rev a2) 00:02.0 USB Controller: nVidia Corporation MCP61 USB Controller (rev a2) 00:04.0 PCI bridge: nVidia Corporation MCP61 PCI bridge (rev a1) 00:06.0 IDE interface: nVidia Corporation MCP61 IDE (rev a2) 00:08.0 IDE interface: nVidia Corporation MCP61 SATA Controller (rev a2) 00:09.0 PCI bridge: nVidia Corporation MCP61 PCI Express bridge (rev a2) 00:0b.0 PCI bridge: nVidia Corporation MCP61 PCI Express bridge (rev a2) 00:0c.0 PCI bridge: nVidia Corporation MCP61 PCI Express bridge (rev a2) 00:0d.0 VGA compatible controller: nVidia Corporation GeForce 6100 nForce 430 (rev a2) 00:18.0 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] HyperTransport Technology Configuration 00:18.1 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] Address Map 00:18.2 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] DRAM Controller 00:18.3 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] Miscellaneous Control 01:06.0 SCSI storage controller: Adaptec AHA-3960D / AIC-7899A U160/m (rev 01) 01:06.1 SCSI storage controller: Adaptec AHA-3960D / AIC-7899A U160/m (rev 01) 01:07.0 Ethernet controller: 3Com Corporation 3c905C-TX/TX-M [Tornado] (rev 78) 04:00.0 Ethernet controller: Attansic Technology Corp. L1 Gigabit Ethernet Adapter (rev b0) In face of this info on the varying behaviour on different motherboards and of the info on my asnwer to Mark Salyzyn's message do you still think this can be a cable/driver/terminator/adapter issue? I ask because it seems unlikely to me but I don't have that much experience on SCSI issues.
