Subject: Too large value in inode.i_blocks[1]

Hello,

Continuing in my adventures with ext4, now I am having
a problem that when reading the root
inode everything is fine. 
When reading the inodes of directories placed on the file system root,
my reading fails, because inode.i_blocks has the following data 
(for 1 particular subdir for example):

127754,
4,
0,
0,
1,
1366,
0,...

The root works because in its inode i_blocks[1] has a smaller, 
in-bounds value, but this one has
the first value completely out of bounds of the filesystem =(

My ext4 filesystem has 3 incompat flags set: EXT4_FEATURE_INCOMPAT_FILETYPE,
EXT4_FEATURE_INCOMPAT_EXTENTS, EXT4_FEATURE_INCOMPAT_FLEX_BG

I suppose it must be related to either EXTENTS or FLEX_BG ...

any ideas?

Also, where can I read about the exact effect of ext4 new features?

thanks,

Felipe Monteiro de Carvalho
