BUT after the second restart the NAND-flash-partition could not be really used after the second mount, dmesg filled with messages: ... jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x03ce0000: 0xc0ff instead jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x03d00000: 0xc0ff instead .... Just for for info: the behaviour observed on mpc8313-based board with the large-page NAND. The only activity on NAND-flash was the garbage collector process, that looks for CLEANMARKER-nodes As Scott said it was broken by commit 3ab8f2a2e7011c5e83363b42950757e46ef06824 Signed-off-by: Sergej Stepanov -- Signed-off-by: David Woodhouse --- Reading git-diff-tree failed
