Hi,
I have problems with my Ovis Link 10/100 PCI Network adapter (based on 
RTL8139too)

Until yesterday the NIC worked flawlessly with Linux-2.4.19-SuSE (from SuSE 
8.1) and rtl8139too (driver version 0.9.26).

Yesterday I exchanged motherboards + Processor (from MSI 6195, K7pro with 
Slot1 K7-700 to MSI 3660, K7turbo with Socket A 1.2 Thunderbird) and added 
256MB RAM (now 512MB).

The old motherboard had a AMD751 Irongate chipset, the new has a Via 
KT133A(552BGA)/VIA686B(352BGA) chipset.

Now the network connection is sometimes "stuck" for ~1-2 seconds every ~30
seconds, "dmesg" outputs the following:

eth0: Too much work at interrupt, IntrStatus=0x0001.

I googled around a bit but all I could find was the advice to try another
PCI slot (tried it - but helped nothing) and to replace the cheap NIC to a
better quality one.

Oooops - while writing this and opening the Acrobat Reader I received
multiple kernel panics:

Well - this could be due to these buggy nvidia drivers. :-(

Anyway, do you have another suggestion to the network card problems - except
replacing cards - or is this just a incompatibility between the 8139 chipset
and the Via KT133A chipset?

                Best Regards,
                Hermann
