+
+To ensure that card is in a sane state during probe we add a reset call.
+This change was prompted by users of kdump who was not able to bring up the
+wireless driver in the kdump kernel. The problem here was that the primary
+kernel, which is not running at the time, left the wireless card up and
+running. When the kdump kernel starts it is thus possible to immediately
+receive interrupts from firmware after registering interrupt, but without
+being ready to deal with interrupts from firmware yet.
