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.
Interesting! Thanks for the diagnosis...
