I have a USB card reader that only worked if I issued "hdparm -z
/dev/sdX", for some reason the device only worked after the second
time it was initialized. I don't know if you're using USB or MMC
interface for your card reader but maybe you can try it.
I have another device that used the MMC driver, it didn't work
properly with fast cards (above class 4) -- massive corruption every
time -- the "fix" was to hardcode the DTO value of 0xA in the mmc
driver (instead of dynamic calculation), after that it worked fine...
