Amit Kale has an opinion and references to discussions:

I have not debugged any kernel modules (yet).  I would probably debug as
much as possible using test harness in userspace, and then use kdb to
avoid the "Heisenbugs" effect. Then again I don't plan on writing large
amounts of kernel code, either.

In the past I have been spoiled by hardware debuggers, and been punished
by having to fight an 8086 without one.  In the latter case, I ended up
building a software debugging environment blind just to be able to
make progress.
