I've just upgraded kernel to 2.6.36.1 and unfortunately some new features in
ext4 are deadly for my setup.
Mounting an external usb WD disk causes at first some dmesg activity:

Nov 25 21:10:01 aquarius kernel: EXT4-fs (sdb1): Unrecognized mount option
"ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ."
or missing value
Nov 25 21:10:01 aquarius kernel: EXT4-fs (sdb1): failed to parse options in
superblock:
ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ
ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ.
Nov 25 21:10:01 aquarius kernel: EXT4-fs (sdb1): mounted filesystem with
ordered data mode. Opts:
ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ
ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ.; (null)

And this is how it looks like with 2.6.35.x:
Nov 17 06:43:28 aquarius kernel: EXT4-fs (sdb1): recovery complete
Nov 17 06:43:28 aquarius kernel: EXT4-fs (sdb1): mounted filesystem with
ordered data mode. Opts: data=ordered

Just after mounting kernel is generating an oops, locking my system completely
(sysrq does not work!).

There are no special options passed to mount at mount time:
/dev/disk/by-label/MyBook    /mnt/mybook    ext4    noauto    0 0
