Description Hiroto Shibuya 2008-03-14 17:00:58 EDT
Description of problem:

http://lkml.org/lkml/2005/8/11/79

Version-Release number of selected component (if applicable):

How reproducible:

100% with the specific sequence below.
Otherwise, only happens in very specific situation that we cannot reproduce.

Steps to Reproduce:
As described in the mail above:
* have via-rhine NIC
* unplug network cable
* reboot box
* force HDX (I do in with ethtool -s eth0 autoneg off duplex half)
* plug cable back
* kernel still thinks that carrier is off despite "ethtool eth0"
  saying that link is detected.

Actual results:

Communcation via the particular interface does not resume 
although the link is up and interface status is UP.

Expected results:

Communication via the particular interface is restored.

Additional info:

The following patch applies cleanly and fixes the problem:

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=00b428c2ab35c81905b3e39d673689216dbd4742

This is non issue in RHEL 5.* which already contains this patch.

Comment 3 Ivan Vecera 2008-05-16 11:23:02 EDT
I prepared the kernel packages (for i686 and x86_64) with the bugfix. Could you
please try them and put here some test report.
Kernel packs are available here:

Comment 4 Hiroto Shibuya 2008-05-19 11:26:01 EDT
Thank you Ivan.  

I tested the kernel through the procedure mentioned above on the VIA 
target machine and the networking restored immediately when the 
cable was reconnected.  It is working perfectly.
