Okay, running and showing us lspci (both -n and -v) output would probably 
help... not that I'm an expert on this and likely to be able to help...

Furthermore knowing _when_ it panics would also be a real boon.

For now, I'm running the -22.0.2 kernel since this is the last kernel
known to work on that hardware. 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.
