[Bug 453579] Re: in-place corruption of large files *without fsck or reboot* reported with linux 2.6.31-14.46 on ext4

[Goffi]

By the way, I made a cmp of the qtmoko files, I have 2 bytes which
differ:

% md5sum qtmoko-debian-v15*
5381503d377dc27b7bb669aa8f0cb43e  qtmoko-debian-v15.jffs2.clean
80d61c5c70f982f6b531d2eb5d536476  qtmoko-debian-v15.jffs2.old
b35355cccc3e93ab08d1e22e05d888de  qtmoko-debian-v15.jffs2.old2
% cmp -l qtmoko-debian-v15.jffs2.clean qtmoko-debian-v15.jffs2.old
16070033  64 164
16070039 257 255
% cmp -l qtmoko-debian-v15.jffs2.clean qtmoko-debian-v15.jffs2.old2
12701898   0 100
12701904  47  45

and for the navit map (the first one is the file I got with my script):

% md5sum australia.navit.bin.zip*
bb13d0594e67cbb4010d6f57de01d91f  australia.navit.bin.zip
