Please check, that SLiRP DNS-Server is the first address.

cat /etc/resolv.conf
  # SLiRP DNS resolver
  nameserver 10.0.2.3
  #alternative servers...
  nameserver 192.168.0.1

Works a typical "wget bigfile.tar.bz2"?
What is different between wget and emerge?

Version 0.6.3 final (5 Feb 2006) has all patches from the 0.7 version 
for slirp code.  In this case, 0.7.1-hn11 and 0.6.3 should have the same 
problem.

Kernel version and coLinux managemants are differ.

The ARP handling for first connect is lightly others.  But should no 
problem, if your linux ip for slirp is all times 10.0.2.15

A known problem: Some big transfers over UDP (NFS) have problem for 
blocksize >3000...4000 bytes.  Currently not solved in 0.6 and henry's 
versions.  That is currently under developing.

Works it for "root=/dev/cobd0"  and/or "root=/dev/cobd/0" without panic?

Please run the colinux debugger before starts coLinux (the first launch) 
and send me your logfile (zipped) please. I will check this.

   colinux-debug-daemon.exe -d -p -s prints=31,misc=31 > debug.txt
