BCM57780 Broadcom ethernet card module failing to load

Post by gridge » Fri Jul 16, 2010 21:10

Hi guys,
I've a failure in loading the kernel driver for the BCM57780 ethernet card. I just installed a fresh Sabayon 5.3, so it's not already patched with all the latest packages (but before doing, unless you tell me this bug is fixed with those patches, I would prefer to connect with the wired network instead of the wireless).
Few info:

spaganpc modprobe.d # cat /etc/sabayon-edition
Sabayon Linux 5.3 amd64 K
spaganpc modprobe.d # uname -a
Linux spaganpc 2.6.34-sabayon #1 SMP Mon May 31 16:00:15 UTC 2010 x86_64 Intel(R) Core(TM) i7 CPU Q 720 @ 1.60GHz GenuineIntel GNU/Linux

spaganpc spagan # lspci | grep -i eth
03:00.0 Ethernet controller: Broadcom Corporation NetLink BCM57780 Gigabit Ethernet PCIe (rev 01)

spaganpc spagan # dmesg | grep tg3
[ 9.964037] tg3.c:v3.108 (February 17, 2010)
[ 9.964108] tg3 0000:03:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16
[ 9.964128] tg3 0000:03:00.0: setting latency timer to 64
[ 9.968767] tg3 mdio bus: probed
[ 9.968772] tg3 0000:03:00.0: (unregistered net_device): No PHY devices
[ 9.969585] tg3 0000:03:00.0: (unregistered net_device): Problem fetching invariants of chip, aborting
[ 9.969663] tg3 0000:03:00.0: PCI INT A disabled

Following existing discussions (see https://bugzilla.redhat.com/show_bug.cgi?id=525966) I tried to add few lines to the modprobe configuration at the startup (I added a file: /etc/modprobe.d/local.conf with the following lines):
spaganpc spagan # modprobe -c | grep install
install tg3 /sbin/modprobe broadcom; /sbin/modprobe --ignore-install tg3
install skfp /sbin/modprobe marvell; /sbin/modprobe --ignore-install skfp

but it did not work. Still exactly the same problem.

Do you have any idea? I tried to look inside the Sabayon forum but I found no threads on this.
Let me know if you need more info!!

Hello, I have the same board and am having the same problem, I know how he does for work but can not fix.

do the following ...

Code: Select all

rmmod tg3; broadcom modprobe, modprobe tg3
this will work, ie the broadcom module must be loaded before the tg3, if you know how to do it at boot, let me know!

^You could try to automate the entry of those commands at start-up. You can do that by adding them to the file /etc/conf.d/local as follows:

Code: Select all

# Here is where you can put anything you need to start
# that there is not an init script for.

local_start() {
        # This is a good place to load any misc programs
        # on startup (use &>/dev/null to hide output)

        # deusr's commands to get BCM57780 Ethernet card module to work:
        rmmod tg3 && modprobe broadcom && modprobe tg3

        # We should always return 0
        return 0

local_stop() {
        # This is a good place to unload any misc.
        # programs you started above.

        # We should always return 0
        return 0
Give that a try to see if it does what you want. Another approach would be to do what jordanwb did in the following post: [Solved] Netgear GA302T - driver issues
