Comment 1 Daniel Walsh 2011-10-07 14:11:23 UTC

 uname -r
3.1.0-0.rc9.git0.0.fc17.x86_64

But this has been happening the last few kernels.

Comment 2 Dave Jones 2011-10-07 16:13:26 UTC

thanks. Just reported this to netdev.

Comment 3 Chuck Ebbert 2011-10-18 03:44:13 UTC

Fix:
http://git.kernel.org/?p=linux/kernel/git/jkirsher/net-next.git;a=commitdiff;h=a90b412cb8c7ccc1689f9ea130883d00a1f0a5bb

It says this only happens on half-duplex connections. Is that what you have?

Comment 4 Daniel Walsh 2011-10-18 15:10:29 UTC

Not sure, how do I check?

Comment 5 Dave Jones 2011-12-06 17:49:02 UTC

ethtool eth0 (or whatever the interface is named).

Is it still happening with current rawhide ? (that patch is included in current builds).

Comment 6 Daniel Walsh 2011-12-06 20:45:08 UTC

I have not seen this for a while.
