Both tcpdump traces show exactly what I would expect.
NFS is writing in 32K chunks nice and steadily achieving abuot 1M per second.
The "device eth0 entered promiscuous mode" messages are caused by
tcpdump starting and stopping.
The patch in Ubuntu bug 585657 was actually committed to the upstream kernel in
august 2010 and is definitely in openSUSE 11.4.
I suspect that what your sysinfo plasmoid is really showing is a load average
of '2' rather than CPU utiliation of 200% - otherwise top would show something
as you say.
You can confirm by looking at 'uptime' output.
A load average of 2 is nothing special and normal when writing constantly.
The crash sounds very strange - I cannot tell if it is related to NFS IO or is
just some X-server wierdness.
But it sounds like the problem is with KDE, possibly in Dolphin or in KIO
as it is only the KDE UI that slows down.
So I'm going to re-assign this to the KDE team.
Problem summary is that while writing a large file over NFS using Dolphin,
Dolphin and other KDE file action are very slow while the rest of the system is
still quite responsive.
