The patch "libata: kill hotplug related race condition"
introduced the pata_pcmcia error.

Please fix this problem.

    libata: kill hotplug related race condition
    
    Originally, whole reset processing was done while the port is frozen
    and SError was cleared during @postreset().  This had two race
    conditions.  1: hotplug could occur after reset but before SError is
    cleared and libata won't know about it.  2: hotplug could occur after
    all the reset is complete but before the port is thawed.  As all
    events are cleared on thaw, the hotplug event would be lost.
