Migration Problem

Hello,


I 've compile my own kernel 2.6.14 with openmosix. Yesterday on irc, tab sayed
that their is a new patch. Indeed, before this new patch, processes can't
migrate. But this new one allow processes to migrate to another node. However,
I try to migrate some processes. The process migrate but when its execution
finished, the process can't migrate in the other way and a bug appears.  This
is the result of the command dmesg on the remote node.
