Subject: EXT2-FS Error (ext2_new_block) Where is this comming from?? can anyone help

Dear linux gurus,
I have set up a Block Device over a SCSI drive. I write data to the
actual target drive after writing same blocks in my RAMDISK. I am
using RAMDISK of 2 GB. once the allcoated blocks of my RAMDISK are
full i start freeing those blocks (WRITE THROUGH). at this point i
get this message during Write operations
Ext2 FS- Error: ext2_new_block : Allocating blocks in System zone. <block_nr>
Is this some sort of calculation error or some other configuration problem??

This message means that ext2_new_block() got somehow tricked to
allocate a block in the place where inode tables, bitmaps or
superblocks are. I.e. the filesystem is probably corrupted. It's hard to
tell how that happened - you use some standard tools to create the above
described setup or it's just your own kernel hack?

thanks for ur reply Honza ,
that problem was solved .. that was my own kernel hack. and was due to
some calculation bugs
