    iwlwifi: reset card during probe · 4843b5a7
    Reinette Chatre authored
    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.
