Hi folks,
I would like to know if this is regular behaviour:
None of my stamp9g20 will detect a hotplugged sd card. Only a card inserted prior to Linux boot will be mounted. Unmounting this card and removing/reinserting it will not give me access any more, nor will any other card be detected.
Is this an issue with my kernel config, any Linux options, or will I have to cope with it anyways?

Re: SD card removal/insertion
You can apply this kernel patch to enable card detect polling.
Re: SD card removal/insertion
Is there a way to manually make the Stamp detect a new card? Often this might be sufficient just to avoid a reboot.
