there is no such thing as "THE aic7xxx issue". aic7xxx is one of the
first PCI cards that wants an interrupt so if it breaks it usually is a
sign of broken interrupt routing more than anything else.

There are at least 2 issues:
1) motherboards with a 440GX chipset generally come with a broken bios,
these don't work well and are not supported in any version of Red Hat
Linux that come with a 2.4 kernel, although it may sometimes work with
some hacks.

2) a few models of the adaptec hardware appear to have a problem with a
specific driver version as delivered by Adaptec. In such cases, an older
version of the driver (aic7xxx_old) might work; adaptec is actively
fixing the driver and it'll be fixed in a newer driver later on.
