    Unhappy No ethernet card with 2.6.24-20 kernel upgrade

    Some days ago I upgraded my Ubuntu passing from a kernel 2.6.24-19 to a 2.6.24-20.

    Booting with this new kernel 2.6.24.-20, my ethernet card does not work (it is not listed when I do ifconfig -a)

    If I boot with the previous 2.6.24-19 kernel, everthing works fine. Here is it an
    Code:
    lspci
    from it to see which Ethernet card I have:

    Code:
    Ethernet controller: Broadcom Corporation BCM4401-B0 100Base-TX (rev 02)
    	Subsystem: Dell Inspiron 6400
    	Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR+ FastB2B-
    	Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR-
    	Latency: 64
    	Interrupt: pin A routed to IRQ 22
    	Region 0: Memory at ef9fe000 (32-bit, non-prefetchable) [size=8K]
    	Capabilities: <access denied>

    Does anybody have any clue?

    Thanks in advance.

    Here it is (the output is performed launching the command while using the working kernel):

    Code:
    *-network

    According to this your card is recognized by the kernel and the module is loaded You just have to configure it.

    Re: No ethernet card with 2.6.24-20 kernel upgrade

    That was the output from the working kernel, this is instead the one from the 2.6.24-20 kernel which does not work:

    Code:
     *-network UNCLAIMED
           description: Ethernet controller
           product: BCM4401-B0 100Base-TX
           vendor: Broadcom Corporation
           physical id: 0
           bus info: pci@0000:03:00.0
           version: 02
           width: 32 bits
           clock: 33MHz
           capabilities: pm bus_master cap_list
           configuration: latency=64
    Any idea?

    In this kernel; the card is not recognized. Try reinstalling the driver
