I can't really make any sense out of this report. We need more information: what type of machine was being used, what kernel version, which IDE drivers (IDE or libata), for starters. The only thing I can suspect may be an issue is that if you're using the old IDE drivers then you don't have a proper hardware-specific driver for your machine enabled in your kernel configuration. At some point I believe the generic IDE driver was changed to not attach to as many devices as it did previously as it would end up being used in cases where it shouldn't be.
