It has four identical IBM drives, two on each channel. There's always a message saying "target0:0:0: wide asynchronous.", even without "verbose" booting. But in the verbose output below, there is also a line saying scsi0: target 0 synchronous at 80.0MHz DT, offset = 0x3f I assume that the first line should be considered as a debugging message, but the normally not printed second line is the actual device negotiation. Am I correct about that? Are the drives running at 160MB/s synchronous ? Would a patch be acceptable that removes the "wide asychronous" line and would instead output the final settings ? Thanks for your comments, Patrick PS: I will only include the first DV output with "aic7xxx=verbose" Hopefully it's not too long: Uniform CD-ROM driver Revision: 3.20 ahc_pci:2:10:0: Reading SEEPROM...done. ahc_pci:2:10:0: Manual SE Termination ahc_pci:2:10:0: BIOS eeprom is present ahc_pci:2:10:0: Primary Low Byte termination Enabled ahc_pci:2:10:0: Primary High Byte termination Enabled ahc_pci:2:10:0: Downloading Sequencer Program... 422 instructions downloaded ahc_pci:2:10:0: Features 0x1fef6, Bugs 0x40, Flags 0x20485500 scsi0 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 6.2.36 aic7899: Ultra160 Wide Channel A, SCSI Id=7, 32/253 SCBs scsi0: Slave Alloc 0 (scsi0:A:0:0): Sending WDTR 0 (scsi0:A:0:0): Received WDTR 0 filtered to 0 target0:0:0: FAST-5 SCSI 1.0 MB/s ST (1020 ns, offset 255) scsi0: target 0 using 8bit transfers (scsi0:A:0:0): Sending SDTR period 45, offset 0 (scsi0:A:0:0): Received SDTR period 45, offset 0 Filtered to period 0, offset 0 target0:0:0: asynchronous. scsi0: target 0 using asynchronous transfers Vendor: IBM Model: IC35L036UCD210-0 Rev: S5BA Type: Direct-Access ANSI SCSI revision: 03 scsi0: Slave Configure 0 target0:0:0: asynchronous. scsi0:A:0:0: Tagged Queuing enabled.
