The only thing I was suggesting is that because 2.6.28 is the latest 
Ubuntu kernel, that means it's gotten a lot more exposure and testing 
than, say, other options like 2.6.27 or 2.6.29.

I build a fair number of RedHat/CentOS systems with an upgraded kernel 
based on mature releases from, and a config as close as 
possible to the original RedHat one, with the generic kernel defaults for 
all the new settings.  I keep liking that combination better than just 
using an Ubuntu version with a newer kernel.  I've seen a couple of odd 
kernel setting choices in Ubuntu releases before that motivate that 
choice; the scheduler trainwreck described at comes to mind.
