Getting MAC corruption every first time I use ssh in some way

[PrebenR]

When I boot my Asus Eee 1000H (it also happens with a 901) and I want to transfer data via ssh, either by rsync, rdiff-backup, sshfs or scp, I get a MAC corruption error the first time. After this the network is working fine. It has been like this as long as I have had the machine. I have tested extensively and it is not limited problem to my internal network. It also happens elsewhere when trying to copy files from one computer to the other. File size is not important.

I think it must be some error in the atl1e driver. It happens as I said after a boot the first time I try.

Before I haven't bothered with it as it was just to restart the process. But I'm now doing more regular backups and the bug is very annoying as it makes automating the process more difficult and unreliable.

I'm not sure how you want that I debug the problem, so please tell me what to do and I'll provide the data.

I tried to transfer from photos with:
scp -vvv *,jpg 10.0.0.3:/tmp/

From the output I get at the end:

Please advice on how to debug further

Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug did not have the correct package associated with it, which is important for ensuring that it gets looked at by the proper developers. I have classified this bug as a bug in "openssh".

[Charlie Kravetz (cjkgeek)]

Thank you for reporting this issue.

* Do you get this error when just using ssh to the other machine, such as
   ssh 10.0.0.3:/tmp/
* Do you also get this error when trying to scp to /home instead of to /tmp?

Thanks in advance.

I have noticed the bug when I transfer files from one computer to another. Cannot recall getting it when simply doing ssh.

[Charlie Kravetz (cjkgeek)]

Thanks for reporting this bug and any supporting documentation. Since this bug has enough information provided for a developer to begin work, I'm going to mark it as confirmed and let them handle it from here. Thanks for taking the time to make Ubuntu better!

I can confirm this bug. The first scp between two computers (either directly connected via eth or with a switch - we tested many computers) fails with:
Received disconnect from 192.168.252.2: 2: Packet corrupt
