All my tests with om2.6 dosn't work for manually migration (s. test with 2.6.13 
/ posting from 25.10.2005, also a test with 2.6.14 and a mail to Vincent).
Bruce announced another test with 2.6.14 at 23.11.2005 for Kris. He write 
"cnode2 should be live tomorrow :)" but no message about succes.

My question: can anybody write down step by step to build a working om2.6 kernel?

Here is my last mail to Vincent:

I changed my distri from SuSE9.3 to 10.0 (with om-2.6.14-kernel) but the same 
problems, if migration from sendpc to recvpc with a pure-cpu-job:
