Because opening back cover on n900 automatically disconnect sd card slot (which means that kernel cannot flush buffers back to card), filesystem on sd card is always corrupted. So correct solution before opening back cover on n900 is to call sync and umount - to be sure that filesystem is consistent. -- Pali Rohár pali.rohar@xxxxxxxxx _______________________________________________ maemo-users mailing list maemo-users@xxxxxxxxx https://lists.maemo.org/mailman/listinfo/maemo-users
