I upgraded 5 PCs. 3 of them have the exact same hardware and the exact same failure (kernel panic). One of those server isn't in production yet so it would be possible to do some testing. The above informations were gathered from a remote SSH session. I cannot give more details for now and I won't be able to tell more about that problem until next wednesday. Gilles.
