I do think about it before, but because it worked before upgrading, I am
not serios that this is the same.

Yes, I can.

There also was an libc update. Not only the kernel-update. So I can't
really say, what exactly causes the problem.

For now, I do an downgrade to 2.6.30 solve the WLAN-problem, it's more
needed as LAN. LAN doesn't work by now, but maybe in a few days after
the new 2.6.30 is uploaded.

I give the test.patch a try on the weekend and get you informed.

Thanks very much,
Karsten
