Hi, I know that there are a few people who have reported having problems with their scsi card( esp. siig), hanging at boot; especially with the internal cdrom and external scanner combo. I was one of them. A list member previously said that it was caused by having "verbose scsi error reporting " enabled in the kernel. Well I finally got around to doing a 2.4.17 upgrade and my scsi problem at boot disappeared with the following changes. Just disable all "probing of luns", verbose error reporting, "queing checks", and logging. These are all grouped in one section under scsi. I'm not sure which one (or combo) caused the problem, but my scsi no longer hangs on boot with those changes. I'm leaning toward "probing of luns" as the culprit, but who knows. :-) Merry Christmas.
