Hi all, Description of problem: I am trying to install RHEL 4 to a system with the following configuration: - Intel motherbord D946GZ - Intel Pentium 5 (dual core) processor - 2GB corsair memory (DDR2) - 02 SATA HD 160G ( Samsung HD160JJ ) - Adaptec SATA RAID Controller ( to make a RAID 1 with the two disks ) To install redhat I have to use "linux acpi=off noapic" at boot time. Inside anaconda i've made two partition using software RAID, one for swap and other for /. The system install was ok. But, after first boot I had the following problems: - only one processor was detected ( I teste it with a Ubuntu 6.10 CD and it detectd two) - no network card detect ( again with Ubuntu 6.10, it detected a Intel PRO/100, using e100 module ) - rebooting system it gives me some krash memory dump on screen and I have to press reset buttom to reset machine. I try to update it to maybe fix some of this errors. So I added a 3com network card ( don't remember model now) and conected to redhat network. There was more than 400 packages to download. And I selected it to install kernel updates too. After downloading and installing all thse updates, I rebooted system and try to boot with new kernel, but it hangs just after loading the kernel. I checked and the new kernel is also using the boot params "acpi=off noapic". I try with and without params and had no luck. I can still boot with old kernel, but cant detect the two processors. If i remove the acpi=off from kernel boot option, this kernel also hangs and cannot boot. I also updated the motherbord BIOS to latest one from Intel support site. Again with no luck. What can I do to be able to boot with this new kernel??? Version-Release number of selected component (if applicable): RedHat enterprise 4 Update 4 kernel-smp-2.6.9-5.EL kernel-smp-2.6.9-42.0.3.EL How reproducible: yes, on this system. Steps to Reproduce: 1. install base system 2. update and install new kernel 3. try to boot with new kernel Actual results: system does not boot with new kernel version Expected results: complets the boot sucessfully. Additional info: I have to install RHEL 4 on this machine because we are going to install Oracle database on it.

Hi all, I called to redhat support in Brazil and they give some boot param to load the kernel. I tested a lot, like "acpi=noirq" and others, and in the end the boot option that works for me was to load the kernel with "pci=nommconf". I did a basic google to find out that this param is used to install in some machines with Intel Core 2 Duo. http://www.google.com.br/search?hl=pt-BR&client=firefox&rls=org.mozilla%3Apt-BR%3Aunofficial&hs=53q&q=pci%3Dnommconf&btnG=Pesquisar&meta= Using this very nice tip (thanks again redhat support), all my problems have gonne: - two processors detected - network card working ok - reboot working as it should. Please consider this bug can be fixed with this workaround and close it.
