Hi,


The problem is greater than i thought yesterday.

On high load, the ethernet interface eth0 has dma problems, resettings and 
total failures. ( linux itself is accessable from extern and via 
serialconsole)

The Tickets 
Ticket #2506
Ticket #2552

describe a similar or the same problem. But it is not really solved.

I use revision r9340 with:
Linux OpenWrt 2.6.23 #5 Thu Oct 25 19:44:17 CEST 2007 mips unknown

Regards,
Thomas
