Bug Description

Binary package hint: linux-image-2.6.38-3-generic

This sky2 module was working properly on kernel 2.6.35. But on this kernel version causes problems when the network interface is connected to a 10/100Mbps switch. It works properly on a Gigabit switch.

There is a heavy packet loss:

In case anyone wants to try a different driver, I just packaged the latest sk98lin from Marvell. It's working as a sky2 replacement with my Yukon-2 88E8056 chip.

When launchpad finishes the build, it should appear here:

This is also happening on my iMac running Oneiric, kernel 3.0.0-16-generic. Initially the errors seem benign but eventually network performance degrades to unusable speeds. I have no problems if I use the vendor sk98lin driver compiled against the linux-image-2.6.35-22-generic kernel. Foresto's sk98lin-dkms PPA (above) looks like a better alternative (testing now).

However, if I set the boot option irqpoll, it still produces the above output, but at least it doesn't completely fail.

I should add, I tried 3.2, 3.3, and 3.4 kernels, and they all do the same thing.

Using the acpi=off flag seems to fix some of the issues, but then my media keys (for brightness on the imac) fail to work.

There it goes again. With irqpoll it still crashed.

I'm trying the alternative driver.

the sk98lin driver is working well so far. I'll let you know if I run into trouble with it.

Well unfortunately it seems that the 3.2 kernel in 12.04 LTS changed enough to make the sk98lin driver not compile or work correctly (grabbing the source from Marvell).

I really hope that somebody from Ubuntu can triage and patch this already. without the correct driver, ethernet performance is abysmal on many Marvell yukon chips.

I should add, the only workaround to keep the sky2 driver up longer is to modprobe sky2 disable_msi=1. MSI for it seems broken, though the IRQ path still eventually breaks and even causes a kernel panic.

I found a work around, and that is to force the link negotiation to 100Mbps full duplex. At 100Mbps I have no problems, and I can saturate the full 100Mb.

But, when it auto negotiates 1Gbps, then it fails constantly.

Oh yes, the command is ethtool -s eth0 speed 100 duplex full.

Still, I have a full gig connection at my work, and this bug is preventing me from using it.

Vincente Ferrando Berenguer, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command in the development release from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux <replace-with-bug-number>

Also, if you could 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 . Please do not test the kernel in the daily folder, but the one all the way at the bottom. 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. As well, please comment on which kernel version specifically you tested.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream', and comment as to why specifically you were unable to test it.

Please let us know your results. Thanks in advance.
