The tx_timeout code performs a full hardware reset to recover from 
hangs, but it seems that the nic hangs during the hardware reset :-(

The hang could be caused by incomplete tx underrun handling, the 
linuxfet driver resets several registers after a tx underrun.
Could you load the driver with debug=3? For example by adding 'options 
via-rhine debug=3' into your /etc/modules.conf?

If it hangs again, then send the dmesg messages to the mailing list - 
especially the last few lines before the first transmit timeout will help.

Re: bug in via-rhine network-driver (transmit timed out) Final Test-results

Hi,

thanks for the good help - the card works really good now. =)
In the following I'll answer to all of your suggestions in this one
mail:

>Does booting with "noapic" on the kernel command line fix your problems?
Yes, it did.
(Although I don't understand why cause I have no smp-system ;-))

>Have you tried the 8139too driver?  This driver is suppose to work
>too.
No, it didn't work in my tests.

>Try the linuxfet driver found here:
>http://www.viaarena.com/?PageID=87#ethernet
I took the driver for "Red Hat Linux 7.3 VT8231/VT8233/VT8235/VT6105
Fast Ethernet Controller" (07/23/2002 Ver 0.9) and compiled it on my
SuSE-8.1 - and it worked really good :)

Additional I found out, that booting with "acpi=off" also fixed the
problem - but this might be a specific problem of the
SuSE-8.1-Kernel.

To complete the test I'll send the detailed debug-messages tomorrow.

As you said I loaded the driver with options via-rhine debug=3
but in debug-mode there was no error any longer!
I know this is a bit strange but if I get the error-message
again I'll post it...

Here are some system-informations: (with debug=3, no errors)
