Where you captured this:
Code:
[ 22.610798] mmc0: Timeout, intmask=0x00010000
[ 22.615157] mmc0: Trigger MMC Recovery
[ 22.618985] mmcreinit_work_func: Resetting MMC, try=1, total_time=0
[ 22.694722] mmc_reinit: Reinit card
Let it run, at least over night, to see if it can do the recovery.
You can't wear it out any worse than it probably already is.

Keep the USB cable plugged while it runs, you don't want it to run on the battery like that, not for over night.
