Excellent! Scott, could you also post a cmp -l of a corrupted vs a good file?
Now, let's have some binary... (Note that cmp -l output is octal)
% cmp -l qtmoko-debian-v15.jffs2.clean qtmoko-debian-v15.jffs2.old 16070033 64 164 16070039 257 255
064 = 00110100 164 = 01110100
257 = 10101111 255 = 10101101
% cmp -l qtmoko-debian-v15.jffs2.clean qtmoko-debian-v15.jffs2.old2 12701898 0 100 12701904 47 45
000 = 00000000 100 = 01000000
047 = 00100111 045 = 00100101
You have single bit flips on the second and on the seventh bit. This looks so much like broken memory it virtually has to be broken memory.
OTOH, if everybody sees the second and the seventh bit flip then probably ext4 is doing something very stupid. Again, please post your cmp -l results!
