The proper upgrading procedure is described in /usr/src/Makefile
(starting from line ~41). Also check the handbook:

By executing "mergemaster -a" you don't actually merge the files. This
may not update important files.

If you're using customised kernel, then probably you took something
important out of it. Try GENERIC to rule this one out.

I hope this helps.
