We're running FC2 with e.g.
rgb at s00|B:1001>uname -a
Linux s00 2.6.7-1.494.2.2smp #1 SMP Tue Aug 3 09:34:09 EDT 2004 x86_64 x86_64 x86_64 GNU/Linux
It's been pretty stable and gives good decent numerical performance.
Are there particular advantages to FC3 and the more recent 2.6 kernels?
I'm running only one experimental AMD 64 box with FC3 on it (since Duke
has decided to use only every other FC release in production to stretch
the cycle a bit) and don't have an opteron per se set up that way for
