    ath9k: reset after PCI FATAL/PERR interrupts · a89bff9a
    Steven Luo authored
    ath9k_hw_getisr() doesn't appear to set anything in the status mask for
    PCI FATAL or PERR interrupts (AR_INTR_SYNC_HOST1_FATAL/PERR), which
    the open-source HAL seems to do.  This means that the card isn't reset
    after these interrupts.
    This patch seems to fix a problem where the wireless drops out with an
    "ath9k: received PCI FATAL interrupt" in dmesg after some time; the
    hardware is an AR5416 in an ASUS WL-500W running (OpenWRT) and
    compat-wireless 2009-03-31.
