network stop working after I've got sky2 eth0: tx timeout

Binary package hint: linux-image-2.6.15-28-server

I've seen many reports of similar problems with this card, but no one exactely with my kernel.
The mail server was working reliably since about nine month and some kernel update.
The last one was on Sunday to linux-source-2.6.15 (2.6.15-28.55).

The server was rebooted with the new kernel on

May 27 18:29:26 mail kernel: Inspecting /boot/System.map-2.6.15-28-server

Then I tranfered some GB (about 10) on such card without trouble (a network backup).
This morning when the transfer was presumably low (about 60 email clients) in kernel log
I've got:

and then it didn't respond any more. I had to reboot switching off (the server was still responding on another
interface to webmail request, but a firewall didn't allow ssh access from there and the server is headeless

Let me know if I can report some more usefull info.

Is it possible to backport to this kernel the patches introduced in 2.6.20.2 by Stephen Hemminger for this unlucky card
 or do I have to compile a 2.6.20 or 21 to overcome this trouble?
I'd like to do it my self, but sorry, I can't (for me is more easy to compile a 2.6.21, also if I'd like better to continue to use the mainstream Ubuntu kernel for server).

Is this still a problem in the latest version of Ubuntu, Hardy Heron?

[Launchpad Janitor (janitor)]

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this linux-source-2.6.15 kernel bug to the new "linux" package. We appreciate your patience and understanding as we make this transition. Also, if you would be interested in testing the upcoming Intrepid Ibex 8.10 release, it is available at http://www.ubuntu.com/testing . Please let us know your results. Thanks!

[Leann Ogasawara (leannogasawara)]

Setting to "Incomplete" until further response from bug reporter.

[andreaferraris (ced-comune)]

At now the disks of such server have been migrated on different hardware, so I can't provide further testing.

[andreaferraris (ced-comune)]

At now I can't provide further testing because the disks have been migrated to different hardware.

[seisen1 (seisen-deactivatedaccount-deactivatedaccount)]

I will mark it as invalid then, thanks for getting back to me.
