You don't indicate how you are upgrading the kernel, but if you're using the
precompiled Debian kernels, you will need to make sure the raid drivers are
included in the initial ram disk. "man mkinitrd" will help you here.
If you have compiled your kernel yourself, did you either A) compile in all
raid / filesystem support you need or B) add the modules you need to the
initial ram disk?
If you've done the above and are still seeing problems, check out the list
archives for threads on moving the raid start back in the boot sequence.
I'm sorry I don't have the link available.
If none of this helps, please be more specific with your configuration,
differences between what works and what doesn't, and what you've tried so
far.
