Well, I unplugged the scsi drive and:

 bmike1@2[bmike1]$ dmesg
 scsi1: PCI error Interrupt at seqaddr = 0x7
 scsi1: Data Parity Error Detected during address or write data phase
 bmike1@2[bmike1]$              


So the way it looks to me is that the scsi card (is that the adapter) reports
this error since it says:
    
scsi1: Some device on this bus is generating bad parity.
      scsi1: This is an error *observed by*, not *generated by*, this
controller.
scsi1: PCI parity checking has been disabled.
     scsi1: WARNING WARNING WARNING
