VIA Rhine ethernet driver bug

VIA Rhine ethernet driver bug

[Udo van den Heuvel]

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

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

What kernel version are you using? Its important to inform that.

Hi,
 I've the same problem with a VIA EPIA M9000 using the Via rhine controller.
My kernel is 2.6.10-ac7. But the problem can be see with a 2.4.27.
String use to identify the driver:

eth0: MII PHY found at address 1, status 0x786d advertising 05e1 Link 45e1.

It's not a critical bug, but if we can resolv the bug ...

Problem is in all kernel versions since 1999 or so.
I am at 2.6.10-mm2, experimented with older via-rhince.c drivers.

If it drops the link with the net I do think it IS critical.
Most of the time occurences of this bug do make my pppd choke.

ifconfig eth1 down
ifconfig eth1 up

helps.


How can we nail the cause? Fix the bug partly or completely?
Suggestions are very welcome.

Thanks,
Udo

That might be interesting to someone:

My VIA EPIA based machine  was working well until some minutes ago. I
accidently removed the power supply and the machine rebooted. From
then on I didn't have network anymore. The ethernet card (VIA Rhine
II) (static, not dhcp) was not working and "Oversized ...."  messages
were printed on the console.

I've rebooted twice and the network didn't still come up. Pinging a
machine on my LAN and pinging the box back resulted in > 98% of the
packets lost.

So I stopped the machine, let it rest for a minute or so and booted
again. That solved the problem.

So if you see the same message as Udo, try to let your box rest.

VIA Rhine ethernet driver bug

[Udo van den Heuvel]

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
