--- Comment #15 from Karsten Keil 2007-09-20 09:55:03 MST ---
So I installed now RC1 and run into this problem again, HW is i386 with sky2.
This time the network test works, it also downloads the release notes, but
after install was done (without additional reboot) ping <name> doesn't work,
but ping -n <IP> does.
nslookup runs into a timeout.
Running tcpdump on the nameserver shows, that the packets have a wrong UDP
checksum:

A tcpdump on the notebook also shows UDP checksum errors

Strange:
After some minutes (writing this down), it works, without any problems, I
cannot reproduce it any longer.
I do not have any idea.
I'm on vacation and traveling without network until Tuesday.
