Description of problem:
Dual XEON on SuperMicro PRDL6 motherboard. Two SCSI disks. The
installer fails to find any disks. Fedora Core 1 and RedHat 9 are
working on the machine, but with the 2.4 kernel. I have also tried to
install the generic kernel on the FC1 partition, but the driver has
the same problem. I contacted the developer, got the latest driver,
but it has the same problem. The developer suggested this:

sprinkling > printks in the routine ahc_linux_pci_dev_probe() in the file
> drivers/scsi/aic7xxx/aic7xxx_osm_pci.c to try and narrow down the
However, this routine is never reached, and I got no further input
from the developer.

Steps to Reproduce:
1. Attempt to install FC2t3 on machine
Actual Results: installer can't find any disk drives
Expected Results: Install should complete normally
When booting the 2.6.2 kernel with the FC1 install, this message appears:
loading aic7xxx.ko module
insmod: error inserting /lib/aic7xxx.ko: -1 No such device

aic7899 is still not in the Rawhide kernel (but apparently has been
with upstream kernel.org kernels since 2.6.6), and users can't get the
SCSI controller recognised (even though aix7xxx is included, but can't
This on an i386 machine, too
eh the rawhide kernel is based on 2.6.9-rc1; anything "since 2.6.6"
sure is included
Apologies, wrongly informed. This is the i2o stuff, which I think
*just* got merged in... Will tell user, thanks arjan
Has this issue been fixed since this thread was posted? I'm trying to
install FedoreCore2 on an Intel SE7500 machine that also requires a
working AIC 7899 driver. So far, no luck. Anyone know of other RH
distributions that can recognize the 7899?
any improvement with the latest update ?
All was well with Fedora Core 2 (no extra drivers needed) after I
added "acpi=off" to the linux startup line. Looks like there's some
sort of interrupt compatiblity problem...
Fedora Core 2 has now reached end of life, and no further updates will be
provided by Red Hat. The Fedora legacy project will be producing further kernel
updates for security problems only.
If this bug has not been fixed in the latest Fedora Core 2 update kernel, please
try to reproduce it under Fedora Core 3, and reopen if necessary, changing the
product version accordingly.
