For me all versions from cvs and all patches from Pyun are working now,
after I have solved the issue with the bad riser card. I still think it's
funny that the riser causes this kind of trouble for the networking chips.

On the other hand, I have not been able to get more than about 10MByte/s
through the interfaces of this particular system. I have 1GBit-networking
equipment, and the other systems (which are used as router) have no
problem doing a throughput of >20MB/s. Even bonding the two interfaces
using lagg(4) does not improve the performance - where else could be the
bottleneck?
The only difference here is that I have the extra SATA-controller with
disks in there. However, the disks appear to be as fast as I can expect
from a SATA150-interface.
