dmesg of kernel 2.6.31

Hi,

A few hours after starting a server I have these error messages in the e1000 driver. I have these messages for kernel versions 2.6.31 and 2.6.32.

Regards.

dmesg for kernel 2.6.33

Comment 10 Jesse Brandeburg 2010-03-01 17:05:21 UTC

What kind of traffic are you doing at the time of failure, and I guess it is easily reproducible right?  Would you be able to run some debug code for me?

Comment 11 Frederic MASSOT 2010-03-02 18:07:51 UTC

It's a web server in production with many small and medium web sites, no high trafic. Error messages appearing several minutes after boot, but it's random.

I can use some debug code, if it does not go down the server.  :o)

Comment 12 Jesse Brandeburg 2010-05-25 17:54:23 UTC

Hi sorry for the delay, is the issue still occurring?  I guess if you wanted to you could try 2.6.34, not for any particular fix, but just because it is the newest.

I see you have an ICH5 (82865) and do you have 3GB or 4GB of ram?

Please attach output of dmidecode.

Comment 13 Frederic MASSOT 2010-05-26 10:55:55 UTC

Hi,

Yes, I still had a trace on Friday 21. 

In the coming weeks I will test the kernel 2.6.34, but as the server is in production I can not reboot it regularly.  :o)

This server has 3 GB of ram.

I post the output of dmidecode.

Regards.

Hi,

On 23 June, I updated the server to the kernel 2.6.34. I will post the dmesg and config file.

Since I had two times the error messages :

Hi,

I've also the same problem since about one year and just opened a bug here. Now with some other search patterns I've found this, so mine is a clone *sorry*

I've found a patch which fixed the problem for me: see bugreport #16471

https://bugzilla.kernel.org/show_bug.cgi?id=16471

Patrick

Comment 19 Frederic MASSOT 2010-07-27 19:05:32 UTC

Hi,

In my case, the server has 3GB of RAM, not 4 GB.

Regards.
