Description of problem:
Installer seems to hang during the initial 'loading aic7xxx' module
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Insert bootable installation cd-rom
2. Turn on PC
Actual Results: The installer hangs.
Expected Results: The installer completes
This identical problem happened under the 7.2 install, and it was
determined that there was a bug between the 2.4.x kernel running in non-
SMP mode and the aic7xxx card that is embedded into the motherboard.
The solution was that a redhat person uploaded some install images
which were SMP enabled.
(As I recall, it was a problem with the APIC system?)
I guess I should have looked a bit harder, because I was able to get this
working using workarounds from previous redhat versions. It would be nice if
this issue could be resolved sometime, as it seems to have reappeared in every
redhat since 7.1. I don't recall other distributions having the same symptoms
during that time period.
(the 'linux apic' commandline option fixed this one)
It's an Intel bios bug; please contact intel for an upgrade
Also please run the dmidecode program from the kernel-utils
package and attach the output; with that we can make the "apic"
automatic for your exact bios

We have an L440GX+ board that exhibits this problem. The various "pci=", SMP
kernel, and "apic" workarounds did not help. Fortunately, the system we were
installing to had a RAID controller (used a different driver), and an IDE
CD-ROM. So, we did a "noprobe" install, skipped the "aic7xxx" driver, and got a
We then downloaded kernel 2.4.20 (final release, pristine sources), did a custom
build, and tried that. It worked perfectly. It appears that Alan Cox obtained
information from Intel that lead to a fix.
