From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6) Gecko/20040510 Description of problem: I took a system that was running a 2.4 kernel and tried to install Fedora Core 2 over it (straight install, not an upgrade). The Fedora Core 2 only detected the Intel 82540EM NIC that is built into the S2707G2N motherboard. The Intel 82545EM NIC was not detected. After a while, I gave up on Fedora Core 2 and re-installed RedHat 9 over Fedora Core 2. After the re-install or RedHat 9 over Fedora, both NICs were once again detected and functioning perfectly. System Details: (Note - I have actually two systems that are essentially the same. I have seen this problem on both systems. The only difference between then is that one has the 3ware 7500-8 adapter, and the other was a 3ware 9500S-8) Tyan S2707G2N M/B (with latest BIOS v1.07) [all jumpers in their default position] 512MB DDR266 ECC, Registered RAM (Corsair) 3ware 7500-8 (last firmeware from v7.7.0 release) Maxtor 40GB UDMA133 IDE drive 3.5" Floppy 52X IDE CD-ROM (Memorex) The 3ware card is installed in the first PCI-X slot (the one that does *not* share a PCI bus with the embedded NIC). Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Install Fedore Core 2 onthe system above Actual Results: Fedora Code 2 installs, but second NIC is not detected. Expected Results: Expected that the second NIC would be detected Additional info:
One thought just occured to me here. The NIC that is not being detected is on the 64-bit PCI-X bus. The one that is detected is on the 32-bit PCI bus (the motherboard has three separate PCI busses). If you look at my other bug (#125412), the 3ware card that is not being detected was also plugged into a PCI-X slot. Maybe something changed with the 2.6 kernel such that the PCI-X buses are not being detected anymore?
it could be that acpi is ruining the game, could you try acpi=off ?
Interesting. Turning off the ACPI support does prevent this problem. It also solves the problem I reported in BZ# 125412. 'Course, it means that I can't get ACPI support running, which is a bit of a problem for an SMP system as that is the only way that I can get power management. For the time being, I can work with things this way, but I would really like to get *both* ACPI *and* my NIC/3Ware hard running at the same time. Some other data points from various experiments I ran: Problem also occurs with a stock 2.4.26 kernel installed on top of a RedHat 9 installation. Turning off ACPI "fixes" the problem here as well. Problem also occurs with a stock 2.6.6 kernel installed on top of a Fedora Core 2 installation. Turning off ACPI "fixes" the problem here as well.
