    cciss: Ignore stale commands after reboot · b59e64d0
    Hannes Reinecke authored
    When doing an unexpected shutdown like kexec the cciss
    firmware might still have some commands in flight, which
    it is trying to complete.
    The driver is doing it's best on resetting the HBA,
    but sadly there's a firmware issue causing the firmware
    _not_ to abort or drop old commands.
    So the firmware will send us commands which we haven't
    accounted for, causing the driver to panic.
    
    With this patch we're just ignoring these commands as
    there is nothing we could be doing with them anyway.
