[LG Optimus Black] j0ris:
I have regular (about once per day) unmounts since installing the Marvel ICS rom, and have been unable to get rid of the problem.

I reformatted the card on the phone, and copied back not much more than music, pictures and movies. Didn't help: an hour later I got another unmount.

SD-card: Transcend 16 GB Class 4

ROM: Marvel ICS v 1 (4.0.4)

Kernel 3.0.8
