I have observed a issue with ext3 from the beginning. After considerable
digging I am still not sure of the origin or reason.

My grsec patched kernel has all ext3 options enabled as built-in, not
Modules. All the grsec/PAX options are enabled as well.

All my partitions were formatted ext3 with a journal.

Now on boot, the partition mounts with this warning...
EXT2-fs warning (device hdb1): ext2_fill_super: mounting ext3 filesystem
as ext2

-su-3.2# mount
/dev/hdb1 on / type ext3 (rw)
proc on /proc type proc (rw,noexec,nosuid,nodev)
sysfs on /sys type sysfs (rw,noexec,nosuid)
devpts on /dev/pts type devpts (rw,nosuid,gid=4,mode=620)
shm on /dev/shm type tmpfs (rw,nosuid,nodev)

Attempts to mount other ext3 partitions meet this fate:
-su-3.2# mount /dev/hda2 /mnt/x
mount: unknown filesystem type 'ext3'

but I can mount it as ext2 with no problem.

Meanwhile I have mounted my root partition on my another system and run
e2fsck multiple times but when I reboot the times mount times are way
messed up, a check is forced, and I still get this mess:

-su-3.2# tune2fs -l /dev/hdb1

Are there some file system compatibility issues?
I am missing something obvious but the answer eludes me so far.
