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? One thought just occured to me here.

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. *** This bug has been marked as a duplicate of 124572 *** Changed to 'CLOSED' state since 'RESOLVED' has been deprecated. |
