network (eth0) doesn't work after suspend to ram (Marvell 88E8036)

[Eduardo]

After suspend to ram, eth0 (network) doesn't work. Networkmanager-applet says "disconnected" but it is connected.

The card is:
02:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8036 PCI-E Fast Ethernet Controller (rev 10)

I can see a error in dmesg:

I have seen that with ArchLinux with kernel 2.6.32.3 occurs the same. I think is a kernel problem.
If you need more information, ask me, i want to help.
Thanks

Hi. I have confirmed where is the bug. With git bisect I have seen that:

eduardo@eduardo-laptop:~/linux-git$ git bisect bad
c82f63e411f1b58427c103bd95af2863b1c96dd1 is first bad commit

Author: Alek Du <email address hidden>

    PCI: check saved state before restore

    Without the check, the config space may be filled with zeros. Though
    the driver should try to avoid call restoring before saving, but the
    pci layer also should check this.

    Also removes the existing check in pci_restore_standard_config, since
    it's superfluous with the new check in restore_state.

axx, Do you have exactly the same error? Can you check (with "git bisect") if this commit causes your problem?. You can comment at bugzilla of kernel.

Greetings

[axx (axx)]

I don't have exactly the same error as I don't have mentions of
sky2 0000:02:00.0: eth0: phy I/O error
in dmesg.
The symptoms and the hardware ethernet card are the same otherwise.
I'll post an output of dmesg after resume so you can see.

Otherwise sure, how should I proceed to check if the commit causes the problem ?
Startup, suspend, resume and then run "git bisect start" ?

[Eduardo (eduardoperezval)]

Hi. I think git bisect is a tedious way (but simple) for detect a problem in the kernel. First, I recommend you install kernel 2.6.31-rc7 (it works for me) and 2.6.31-rc8 (it doesn't work for me). This is easy. Only download deb packages from here,

http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.30-rc7/
http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.30-rc8/

and install the three packages for your architecture, linux-image...i386 or 64, linux-headers...all.deb and linux-headers...386 or 64. Test if the problem is present in those kernels. If rc7 works fine and rc8 doesn't work, you probably have the same problem that me.

Next step is detect bad commit with git bisect, but this is hard work, you have to recompile entire kernel from git 5 or 6 times. Process is easy, but it requires time.

You first have to clone the Linux kernel git repository. This is the same concept checking out a repository from CVS.

    $ git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git linux-git
    $ cd linux-git
    $ git bisect start

Next, tell git which kernel was the last known-working kernel, and which kernel is known to be not working. For example:
    $ git bisect bad v2.6.31-rc8
    $ git bisect good v2.6.31-rc7

Now, you have to compile kernel. Then, install it and check if problem are present. If so,
    $ git bisect bad

You have more information here, http://www.reactivated.net/weblog/archives/2006/01/using-git-bisect-to-find-buggy-kernel-patches/

Probably, you have the same problem than me.

If you have any question, write.

Greetings
Eduardo

[Eduardo (eduardoperezval)]

I'm sorry. links for ubuntu kernels are wrong (they are for 2.6.30 and not for 2.6.31).

http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.31-rc7/
http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.31-rc8/

greetings

[axx (axx)]

Ok, I'll admit this a little daunting and I don't really have the time to start cloning the kernel git repo and installing different kernels.
I will say though that I said something untrue earlier on, I *do* have the "sky2 0000:02:00.0: eth0: phy I/O error" line in my dmesg output.

I'll keep an eye on this thread though, in case I can contribute differently, test solutions or find the time to install the different kernels as you were requesting.

[axx (axx)]

Also, I don't know if this interesting to the situation, but I've realised restarting the computer doesn't solve this issue. I have to shutdown and power back on to get my interface back. It seems the problems remains if the network card stays powered.

Also, after reboot, I can insert the sky2 module, but can not bring the interface back up using "sudo ifup eth0" (Ignoring unknown interface eth0=eth0).

I'm getting this in Lucid beta.

Hi. I think I haven't the problem when I reboot, but i'm not sure. I will test it this week.

#aysiu
Seems the same bug that I have. Do you have this problem with Karmik koala?

[Jeremy Foshee (jeremyfoshee)]

Hi Eduardo,

If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

The second time...

[Paddy Landau (paddy-landau)]

I've been having this problem:

- Ubuntu Lucid 10.04 (all updates in place)
- Two different machines, one 64-bit and one 32-bit.
- The problem is intermittent. Sometimes it happens on resume, and other times resume works fine.
- Restarting the machine always gets it working again.

[Paddy Landau (paddy-landau)]

Is this the same bug as 605045?

[Paddy Landau (paddy-landau)]

Workaround: Install WICD and uninstall Network Manager.

This bug affects me too, tested on Karlic, Natty, and Debian testing Wheezy.
