Bug Description

SRU Justification:

Impact: The current tg3 driver in 12.04 does not support this new NIC. To have installer support in the next point release (12.04.3) we need to backport some patches which were added after 3.8 into Raring.

Fix: Backport/cherry-pick of a set of 5 patches. The first one adds basic infrastructure but was not enough to enable the NIC. Number two would do that. The remaining three patches are very small bug fixes which seemed to be related to enabling the new hardware.

Testcase: Boot Raring kernel on OCP v3 hardware. The current driver will not support the network card. With those patches applied it was working.


The AMD OCP v3 "Roadrunner" uses the broadcom (bcm) 5725 netextreme card. 12.04 LTS does not recognize the card (in the PCI ID list or the tg3 kernel module). The PCI ID is 14e4:1643.

My next plan is to try newer point relese, iterim release, and daily build.

I've not check to see if this PCI ID is in the tg3 driver.

I've tested with 12.04.2 and 13.04 and this component is not recognized as a NIC (eth0). I changed the status to critical since it is a cert blocker.

Saucey does work, and the kernel module is "tg3".

Related to this same component is the ipmi/bmc on this bcm5725:

    tg3: Add support for new 5762 ASIC

Changed in linux (Ubuntu):
status: Incomplete → Fix Released

Hi David,

When you have a moment, could you test the following Raring kernel I built which includes the commit I noted in comment #4. I also provided the headers package in case you need them. Anyways, please test and let us know your results (be sure to install both the linux-image and linux-image-extra packages). Assuming positive test results, we can make sure this is propagated back via the Raring HWE kernel in Precise. Thanks.

I Leann, I tried the 3.8 kernel you provided. Unfortunately it does not make the tg3 driver aware of the NIC (and nothing shows up w/ ifconfig -a).

BUT this kernel DOES make the impi_si model work ( ). Not really relevant here I guess.

The apport information is when running the kernel from comment #5. That kernel makes the ipmi_si module work, but the tg3 NIC driver does not work (does not show up as a nic device).

Be aware, in order to get the machine on the network I added a PCI NIC card that shows up as eth10 (a realtek card), but it is not normally found in this machine and not part of this bug report. This bug is about the tg3 driver.

summary: - Add support for Broadcom 5725

Maybe (3) and (4) are not strictly required but since (2) (and (1) too) handle the 5725 and the 5762 in the same context, I thought it would be good to pull those obvious fixes, too. And (5) would be coming through stable if 5725/5762 would have been in 3.8.

kernel from #23 works w/ tg3! I also tested ipmi just to make sure it works.

Will this fix make it into the 12.04.3 LTS point release?

The only things to note, but don't hold up this bug from closing, is

1) The NIC shows up as eth11, but I suspect this could be due to this not being a stock image (using an addon card in the past), etc... but it still works

2) The first time I tested ipmi and reboot the BIOS stopped and said "The BMC is not responding, press <ESC> to continue"... but doing the exercise again didn't cause that to happen.

But let's not have that hold up this enablement fix... I'll do more testing sometime and open new bugs if there are other issues.

I just submitted for SRU and should get into the next SRU cycle which hopefully will make it into 12.04.3. You will get another request for testing the proposed official kernel and then the bug would auto-close as soon as that gets released. I won't fiddle there manually. ;)

1) That may be an effect of using the same image and that having used up the other eth numbers for other MAC addresses in /etc/udev/rules.d/70-persistent-net (or so).

2) Sounds a bit odd but yes it should not prevent us from progressing. As long as basic network works the machine can at least be installed. Oddities could be fixed up later. And maybe it was just random. Does the hardware have a separate management port or is that shared with the tg3?

The BMC physical port is shared with the tg3 (5725).

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed' to 'verification-done'.

If verification is not done by one week from today, this fix will be dropped from the source code, and this bug will be closed.

See for documentation how to enable and use -proposed. Thank you!

I did a fresh install but add an add on nic in order to get the proposed (27-40). Once the proposed kernel was installed the tg3 driver worked fine.

Two gotchas the add on card showed up as "p3p1" device name, and the tg3 nic "p7p1"...

I was expecting this kernel to fix as well... but it is still broken in raring-proposed.

I'm going to change this bug to certification-done, as it does fix the tg3 driver.
