Hello,

On my firewall (VIA EPIA CL-6000 with VIA Rhine network chips running FC3
and custom kernels) I see messages like:

Jan 13 19:35:46 epia kernel: eth1: Oversized Ethernet frame spanned multiple
buffers, entry 0x4 length 0 status 00000600!
Jan 13 19:35:46 epia kernel: eth1: Oversized Ethernet frame ccf80040 vs

every 3 or 4 days or so when I really use the card. (please notice all 16
entries are used and the length is 0)
Eth1 is connected to an Alcatel Speedtouch Home at 10 Mbits, Half Duplex.
This problem did not occur when I wsa using other hardware for the firewall.

While googlin' I saw that this is an old bug which was not fixed for years.
I am in contact with the maintainer and currently am trying to see what
effect a smaller mtu and/or older driver versions might have.

Because of the impact of this nasty bug (many users have these chips in
their hardware) I would like to ask if others could have a look into this
problem as well. Please email me your experiences (2.6.x kernel? Same bug or
no problem? Fixes? Etc).
PLEASE help!

Thanks,
Udo

Hello,

On VIA-Rhine ethernet chips that give errors like:

Jan 13 19:35:46 epia kernel: eth1: Oversized Ethernet frame spanned multiple
buffers, entry 0x4 length 0 status 00000600!

(for all 16 entries)

Setting the mtu to a lower value than 1500 appears to help (tested at 500,
and 1000 is in progress).
Could this give a hint to the cause of the bug?


Kind regards,
Udo

Hello,

I posted about the VIA Rhine ethernet bug to the LKML but received the
suggestion to also post here.
Let me explain about the bug, it gives messages like:

Apr  8 18:51:08 epia kernel: eth1: Oversized Ethernet frame spanned multiple
buffers, entry 0x9 length 0 status 00000600!
Apr  8 18:51:08 epia kernel: eth1: Oversized Ethernet frame cca77090 vs

Apr  8 18:51:08 epia kernel: eth1: Oversized Ethernet frame cca77070 vs
cca77070.
Apr  8 18:51:08 epia kernel: eth1: Oversized Ethernet frame spanned multiple
buffers, entry 0x8 length 24436 status 5f748d10!
Apr  8 18:51:08 epia kernel: eth1: Oversized Ethernet frame cca77080 vs
cca77080.


Most of the time the ethernet connection is gone and needs and ifconfig
down/up or reboot to make it work again.
I see this error on a VIA EPIA CL-6000 board. Using google I see the
mentionings of the error messages in relation to VIA Rhine go back to 1999.
The other side of eth1 is an Alcatel Speedtouch Home. With different
firewall hardware (Tulip DT5/xxx but same Alcatel) I did not see the errors.

Any ideas? A patch to gather more info so the bug can be fixed?
Etc?

Please post!
