And I really don't understand what you're complaining about: if you just need a stable, production quality 2.2.x Linux kernel then grab the latest MontaVista version, configure, build and run. Dan (and others) have pointed this out several times before. If you need something more recent than 2.2.13 for some reasons you can try using the BetKeeper tree (2.4.0-test1-ac21 or so at the moment). This is where current work is going into. > serie.

Complex operations like compiling a kernel Porting those changes back to 2.2.xx with x > 13 seems just a waste of time to me. You will throw all this away as soon as 2.4 is stable. Is there any special reason you can't use the 2.2.3 MV sources?

A bug is a bug is a bug, no matter how difficult it is to trigger in test cases. It will become the show stopper in your first presentation for the most important customer.
