Description Jason Mours 2011-12-23 22:45:46 UTC

I have an embedded Broadcomm 95721 Tigon3. I've compiled <*> tg3 into the kernel with <*> Broadcomm PHY'S. Softlinked net.lo to net.eth0. Tried both in runlevel boot & (currently) runlevel default. .lo comes up and .eth0 hangs @dhcp & ssh fails. After I log-in as root on console and initialize it with '/etc/init.d/net.eth0 start' it brings up the adapter and obtains IP. But not durning boot. I noticed I had to start it (eth0) manually with the LiveDVD 10.1 when I was building it. Let me know if you need any files or output.

Reproducible: Always

1) [Relevant] dmesg output would be nice.
2) Please post the output of the relevant `emerge -vpq sys-kernel/?-sources' in a
   comment.

Interestingly, though:

   To compile this driver as a module, choose M here: the module will be called
   tg3.  This is recommended.

What happens if you build it as a module?

BTW: Not sure what to do about the metadata error in portage. I guess I could erase it and get a new -latest or rsync from scratch

Comment 3 Jason Mours 2011-12-28 02:09:46 UTC

Just rebooted. It's running kernel 3.0.6, It's configured as module by default using the kernel-config off of a minimal installcd from a month or so ago.

dmesg|grep tg3 shows the module is in there,
tg3.c:v3.119 (May 18, 2011)
tg3 0000:04:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16

tg3 0000:04:00.0: eth0: Link is up at 100 Mbps, full duplex
tg3 0000:04:00.0: eth0: Flow control is on for TX and on for RX

Running the net.eth0 scripts starts dhcp after I get into a shell,
I tried compiling it in after reading a thread on the forum. Is there something else I need to look for in dmesg?

Are you still having issues with later kernels?
