I also noticed some oddities with the Fedora x86_64 kernel at the
time on
them (memory leaks) that went away when I switched to using
kernel.org
kernels. I've not had time to look into that further or to see if current
Fedora x86_64 kernels behave better on them....
A patch for this issue is known and should be applied to FC3 before it
ships.
