[ connection response delays in networking code when 2nd drive added ... ] > 1 - Pentium 120 > 40meg ram > Adaptec 2940w PCI SCSI Controller > 2 - Digital DSP3210 2.2 gig SCSI-2s > 1 4xCD-ROM, Sony SCSI Sorry for the delay in response... and after I was the one who asked for more information. I can't explain why adding a second SCSI disk could cause this problem, unless it's a "green" disk that has spun down. Most likely, there is a tagged command queue problem. Depending on which version of kernel you are running, you may need to enable *at least* as many queues as you have drives. On the other hand, it may be a bad queue interaction if they are enabled by default (I don't have a 2940 -- I run NCR controllers), in which case you might need to disable them. Basically: toggle the things and see if it helps. If you still have problems, you'll need to contact the driver maintainer.
