I have had failed CF cards act like this and work fine after a power cycle for
awhile... what I "THINK" happens is that the wear levelling in the car gets to
the point it responds too slowly to the kernel.. the eventual result will be
linux remounts the card read only after so many failed reads / writes..
the cards i lost in the field would test perfectly fine with linux and windows
utilities... put them back into service in the soekris and same errors would
come back after a few days.... or sometimes a few hours
