incorrect MTU size. Command 'ifconfig eth0' show MTU:1500,
but network failed with packet large more than 1024.
Modifying the mtu of the ethernet interface to 1024 
with command 'ifconfig eth0 mtu 1024' make it to work.

Kernel version Linux ubuntu 2.6.28-14-server, Linux 2.6.29.06-std122
Comment 1 Andrew Morton 2009-07-29 23:34:00 UTC 
You state that it's a regression.  Since which kernel version?  In other words, what is the most recent kernel version which is known to not have this bug?

And which driver are we talking about?  sis900.c?
Comment 2 WIPAT SRUTIPROM 2009-07-30 10:13:14 UTC 
Sorry for incompleted information.

The driver is sis190.
Max MTU is 1496.

I've reported to bugzilla(9467) http://bugzilla.kernel.org/show_bug.cgi?id=9467

I've not use this NIC for long time and can't remember what is the most recent 
kernel version which is known to not have this bug.

drivers/net/sis190.c

It's a regression, but we're not sure since when.
Comment 4 dan 2009-09-19 02:55:13 UTC 
You said that it was a mtu issue, after you changed it did you have to do anything else because I have changed it multiple times with no success.

I do no more anything.

I think that this is not a regression, I have not been able to see this problem resolved. see bug 10694
Comment 7 Juan Jose Pablos 2010-04-20 15:13:11 UTC 
Any update on this issue? I want to help, but I need to know what information do you need to resolved.
Comment 8 Juan Jose Pablos 2010-04-21 00:41:50 UTC 
I think that this is duplicate of  Bug 10895. Reported by the same person. So one of them should be closed.
