Weird network problem

[Emiel Kollof <coolvibe@xxxxxxxxxxxxxxxx>]

Hi guys,

I have this really odd networking problem since I cvsupped my HEAD 
system today. The thing serves NFS and samba. Sometimes NFS and samba 
(or any other service, like ssh) will just freeze up (not the server 
programs, but the connections). The problem stops when I press a key. I 
wedged a toothpick into the keyboard so a key is always pressed and the 
problem went away.

Is there something going on wrt the keyboard interrupts and the new 
MPSAFE networking stuff? Has anyone experienced the same thing?

I can upload a kernel to leaf is that's needed.
