I'll include the contents of the file
ftp://ftp.redhat.com/pub/redhat/redhat-4.0/updates/images/i386/scsi/README
which includes a list of affected drivers and instructions for using the
fix provided.
This information soon will be added to the Intel errata available at
http://www.redhat.com/support/docs/rhl-intel/rh40-errata-intel.html

"Ever wonder why the SAME PEOPLE make up ALL the conspiracy theories?"
These boot disks are designed to work around bugs in the Linux SCSI
subsystem; some SCSI adapter drivers do not work as modules. A patch
is available which fixes the problem in a generic way, and it will be
included in a future version of the Linux kernel and a future version
of Red Hat Linux, but the easiest way for you to install Red Hat Linux
now is with these boot disks which have the adapter drivers compiled
into the kernel. You will need to take a few extra steps during the
installation; they are detailed here.
First, you need to choose one boot image:
boot1740.img.gz Adaptec 1740/1742 adapters
boot53c8xx.img.gz NCR/Symbios 53c8xx adapters
bootFlashPoint.img.gz *Beta-test* BusLogic FlashPoint adapters
bootadvansys.img.gz All supported Advansys adapters
bootaic7xxx.img.gz Adaptec 2740, 2840, 2940, 3940, and friends
bootaic7xxx-alt.img.gz Alternate aic7xxx driver if the normal one fails
booteata_dma.img.gz DPT EATA-DMA adapters
The boot image bootaic7xxx-alt.img.gz is built with the aic7xxx driver
from the 2.0.12 Linux kernel. Some aic7xxx cards which do not work with
the current aic7xxx driver worked with the old one, and so if the new
one does not work for you, you can try the old one.
The BusLogic driver is not affected by the bug, but FlashPoint
adapters are not supported by the standard kernel. This BETA-test
update provides FlashPoint support, and needs to be installed in
the same way as the other drivers here.
Use these steps to take advantage of the correct boot image for you:
o Download the appropriate boot image in binary mode.
o Use gunzip to uncompress it.
o Use dd (or rawrite) to write it to a floppy, creating your boot image.
o Boot it and do a normal installation or upgrade.
o When the installation or upgrade has finished and the computer
reboots, put the boot floppy in the drive and boot off it with
the boot command:
linux root=/dev/sd??
where "sd??" is the root partition on which you installed Linux.
o After booting, mount the boot floppy, probably like this:
mount /dev/fd0 /mnt/floppy
o Then copy the kernel image from the floppy over the default one
provided with the system:
cp /mnt/floppy/vmlinuz /boot/vmlinuz
o Re-run lilo:
lilo
o Shutdown and reboot:
shutdown -r now
At this point, you should have a working Linux system.
