Red Hat Bugzilla – Bug 205647
hardware not detected on IBM xseries 300

Description of problem:
I started my install of RHEL5 beta from cdrom, and discovered no disks or
network detected, so I booted back into RHEL4 and looked at the modules loaded
there. Modules of importance were (scsi_mod, aic7xxx, e100). lspci from RHEL4
shows the disk controller as adaptec aic-7892a u160/m, and the network
controller as intel 82557/8/9 Ethernet pro 100.
I decided I'd try to load the modules myself, so I switched to ctrl-alt-F2 and
did a modprobe on aic7xxx, then ran lsmod only to find the module not listed.
Now, I figure I'm just new to this ram disk setup, so maybe it's not possible to
do this. So back in the installer, I choose to add a new device and picked the
aic7xxx out of the list. This time when I checked lsmod, it showed up in the
list properly, but fdisk -l shows no disks. dmesg shows no disks created either.
One other interesting thing to note, is that I can't run lspci from the RHEL5
install on this box either. No results are returned.
I have this machine available to test on, so I'm more than willing to help
Version-Release number of selected component (if applicable):
After additional testing, I found that if I passed the kernel boot parameters
"noacpi acpi=off", the install detected the disks and hardware just fine. So
there seems to be an acpi issue for the xseries 300.
