Comment 66 for bug 76489

I *had* exactly the same problem on ubuntu 9.04 with linux-image-2.6.28-13-server.

I have found something interesting in the last kernel changelog (2.6.30):

http://kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.30

"""
commit fd4d34295b36c5d9a1aba3d3f2764d721db093be

    Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6

    * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6:
      cls_cgroup: Fix oops when user send improperly 'tc filter add' request
      r8169: fix crash when large packets are received
"""

So as not to do apt pinning on my distro, I have only downloaded the last kernel 2.6.30 from karmic repos:

$> wget http://packages.ubuntu.com/karmic/i386/linux-image-2.6.30-9-server/download
$> dpkg -i linux-image-2.6.30-9-server_2.6.30-9.10_i386.deb
$> reboot

And now, it works fine ! It will be ok while waiting for the next ubuntu release.
