As usual, I'm ready to test anything you throw at me:
notaz: I guess that new testing kernel would also work with our current OS? If we start to test a new kernel AND a new OS image, it might sometimes be hard to tell if bugs derive from the kernel or the .next image.
If I could test the kernel on our current image as well, it should be easier to tell.
The problem of the kernel/OS image is that there are some userspace programs that tightly interact with the kernel. Basically resulting in a "too old" version of the kernel and a "too new" version of udev possibly being problematic. The same is of course also true when exchanging those two for each other. There are possibly other programs that also rely on features only available in more recent kernel versions. On the other hand a "too new" kernel might have removed some (by now deprecated) interfaces, that older programs still rely on. One rather important thing that was deprecated is the proc interface (or was it sys?),
So combining the "rather old" (more than 2 years!) kernel .27 with the latest angstrom might lead to some problems, as will some problems that dropping the latest kernel into the current firmware creates only be fixable by more recent userspace programs, which I expect to possibly become a mess rather soonish...
