    ahci: use 0x80 as wait stat value instead of 0xff · dfd7a3db
    Tejun Heo authored
    Before hardreset, ahci initialized stat part of received FIS area to
    0xff to wait for the first D2H Reg FIS which would change the value to
    device ready state.  This used to work but now libata considers status
    value of 0xff as device not present making this wait prone to failure.
    
    This patch makes ahci use 0x80 for the wait stat value instead of
    0xff to fix the above problem.
