I have two machine A and B, each with a 39160 card (aic7899 processor), the Installatioin Guide of the card says, "The Adaptec SCSI Card 39160 has two INDEPENDENT SCSI channels, ...". I use Nate's scsi_target on A, and my test_write_scsi.c on B to write to Emulated Disk uninterruptedly, it works perfectly. Also using scsi_target on B and test_write_scsi.c on A works perfectly. But when I use the two at the same time, kernel code of scsi_target crash like this: Fatal trap 12: page fault wihle in kernel mode ...... Stopped at targdone + 0x84: movl %eax, 0x20(%edx) <<<<<<<<Dump Card State Ends>>>>>>>> ahc1: Bus Device Reset on Ahc0(0:5:1) SCBS aborted. =========This is my enviroment and test: A# dmesg |grep SCSI ahc0: <Adaptec 3960D Ultra160 SCSI adapter> port 0xc800-0xc8ff mem 0xe5202000-0xe5202fff irq 10 at device 15.0 on pci1 aic7899: Ultra160 Wide Channel A, SCSI Id=7, 32/253 SCBs ahc1: <Adaptec 3960D Ultra160 SCSI adapter> port 0xcc00-0xccff mem 0xe5203000-0xe5203fff irq 11 at device 15.1 on pci1 aic7899: Ultra160 Wide Channel B, SCSI Id=7, 32/253 SCBs A# uname -rm 4.7-RELEASE i386 A# scsi_target 0:5:0 B# camcontrol rescan 0 B# ./test_write_scsi B# scsi_target 1:5:0 A# camcontrol rescan 1 A# ./test-write_scsi any ideas?
