Arghh, completely forgot about this... Andy is right, maybe there
are
other cases (in which case, it would be nice to share :D), but
this one
is definitely one of them:

You can have a cmdline parameter to panic on _WARN() and some
systems
may have it.
Yes, I meant panic on warning.
And I can't imagine that this driver can be system critical to the
extent
that we have to crash the system.
Is there something which does trigger a backtrace, but without
panic()ing the system ?
Nothing I'm aware... Other than directly call 'dump_stack()'
All right, dev_err() it is then. I sent V2.
