hm, but dione has been running the same 2.6.24.7-92.fc8 kernel for a 
long time:

/var/log/yum.log-20080528:May 27 23:44:36 Installed: kernel - 2.6.24.7-92.fc8.x86_64

and has 6 days uptime at the moment and no trouble communicating with 
any other buildbox - except the [only] one running latest -git.
