just FYI: I've found this hardware locally, node is free for investigation.
I'm reinstalling Centos to this node right now and then I will try to reproduce
reported issue.

I can confirm this issue,
upload to this node is normal, but download is slow.

FYI:
I've recompiled driver from sources (atl1-1.2.40.3) and it works well on 2.6.18-028stab083.1 kernel.

For certain reasons, this is a bit time-consuming for me to test, but
I'll leave your message flagged as needing further work in case I find
time for it.

I've already tried lowering the MTU (1400, etc.) - this did not help.

5. If you see this message (or lots of them) in your system log:

atl1 0000:02:00.0: hw csum wrong, pkt_flag:1600, err_flag:80

No, I am not seeing any messages like this. No complaints from the
driver at all.

I think I need to emphasize that things work just fine from OpenVZ
containers on the same system! No problems at all. The problem only
shows up when transferring something from the "host system" (CT0).
So it looks OpenVZ-related, not just driver-related.

Thanks,

Alexander
