I'm not sure this is the same problem reported earlier, but it sure is a pain. When the AIC-7896 is probed, there is a ~6 second delay for every bus ID on both channels, accompanied by the error messages indicating: - Attempting to queue an ABORT message - Command already completed - scsi: device set offline - not ready or command retry failed after bus reset: host 1 channel 0 id n lun 0 I will send the verbose output to Justin. This is a stock 2.4.6 kernel, with the linux-aic7xxx-6.2.0-2.4.6.patch applied. The AIC-7896 is on the motherboard of a VA-Linux 2200 system. There are no SCSI devices or cables attached to either channel. It may be just a coincidence, but I am getting a similar behavior on a qLogic QLA2200 FC adapter that is also in the system. It delays 6 seconds for each SCSI ID 0-255, printing: kernel: qlogicfc0 : scsi abort failure: 4006 kernel: qlogicfc0 : abort failed kernel: qlogicfc0 : firmware status is 4000 3 kernel: scsi: device set offline - command error recover failed: host 0 channel 0 id 255 lun 0 Is this coincidence, or something in the mid-layer? -- Tom Coughlan Mission Critical Linux tel: 978-606-0262 coughlan@missioncriticallinux.com "Justin T.
