    libata: Apply NOLPM quirk for SanDisk SD7UB3Q*G1001 SSDs · 184add2c
    Hans de Goede authored
    Richard Jones has reported that using med_power_with_dipm on a T450s
    with a Sandisk SD7UB3Q256G1001 SSD (firmware version X2180501) is
    causing the machine to hang.
    
    Switching the LPM to max_performance fixes this, so it seems that
    this Sandisk SSD does not handle LPM well.
    
    Note in the past there have been bug-reports about the following
    Sandisk models not working with min_power, so we may need to extend
    the quirk list in the future: name - firmware
    Sandisk SD6SB2M512G1022I   - X210400
    Sandisk SD6PP4M-256G-1006  - A200906
