Well, yes.  That's, er, why it's called "testing".  :-) You're  
comparing apples to oranges.  If you upgraded a 2.4 kernel sarge  
system (which was a stable release) to etch (which uses 2.6.18) you'll  
probably find it goes quite well.

If you're running production services off the testing track, you can  
probably expect to get burned occasionally.
