Yes, umount / reboot command doesn't hang after first boot + wait for
20 minutes. The jffs2_gcd_mtdx will re-erase empty blocks but how do I
know it is finished?

BTW, why jffs2_gcd_mtd need to re-erase empty blocks and it will cause
some command cannot work if erase block is necessary. I mean many
pepple could meet this problem if it is need to erase empty block and
how do they overcome or workaround it.

Thank you so much, Jocke
