I'm not having this exact issue, but i am having something alike and i think it should be easy to solve.

In the past, when i wanted to change my uSD i just took off the cover, slide the card out and then insert a new one or the same one, and for the moment the back cover was again on position the phone would have the "new" card mounted and accessible.

But now, after this last update, card is not remounting so i have to reboot my phone, then it mounts it.
Also i'm seeing a "boot" partittion?... ¿isn't that a little dangerous?
And some times after remount them it shows two "memory card", one is with a (2) on it's name. This is a HUGE issue because the one with the (2) sometimes is the card and sometimes is "boot".
I think is a dangerous step back, not for me but just in the case anyone not too familiar with my phone could play around with it and mess around.



¿How could i solve the not remounting issue?
I have tried the reinstall ke-recv but there is no change on the behavior.
¿Should i extract manually the file from .deb?

Thanks.
