The kernel component in Bugzilla is indeed the right place (though you
may also consider filing it upstream at bugzilla.kernel.org). As for
data to include, everything from this post (and the followup) is a good

Quite a lot of devs use Thinkpads, so it's usually not too unlikely
that it'll get fixed. :) Thanks!
