It does expand on i386 exactly because the watchdog is disabled by default.
Looks like a mistake to me. It should be on because having usable backtraces
on a deadlock/hang is useful enough that it outweights any other possible
disadvantages. That's especially true for kernels out there at user's boxes,
not just special debugging kernels run by developers.
[if there should be any hardware where it doesn't work it should be blacklisted
there]
