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 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):

Re: No ethernet card with 2.6.24-20 kernel upgrade
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

bus info: pci@0000:03:00.0

Any idea? :confused:

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

Hi,
first of all thanks for the reply.
But, what do you mean exactly by "try reinstalling the driver"? I mean, up to now I haven't installed any driver manually, everything worked fine...
I feel it strange if I had to tweak manually my system after a simple upgrade....

Try this: open up all your repos except src and do a:
sudo apt-get update
sudo apt-get dist-upgrade

Thanks, I did like you proposed and it works now :-)
