Description of problem:
After resizing a partition on a LVM logical volume, kernel issues some warnings
and finally oops.

Version-Release number of selected component (if applicable):
kernel-2.6.17-1.2139_FC5
e2fsprogs-1.38-12

How reproducible:
Don't know.

Steps to Reproduce (these are the actual steps that were taken):
1. Extend a lv with lvm:  lvextend -l +1 /dev/vg0/disk
2. Use ext2online: ext2online /dev/vg0/disk
3. Watch the kernel log for errors
  
Actual results:
Kernel log:

You end up with a lot of these:
EXT3-fs warning (device dm-1): dx_probe: Unimplemented inode hash depth: 0x0070
EXT3-fs warning (device dm-1): dx_probe: Unrecognised inode hash code 87
init_special_inode: bogus i_mode (71563)

Culminating in:
EXT3-fs error (device dm-1): ext3_find_entry: bad entry in directory #24682062:
directory entry across blocks - offset=0, inode=2099261488, rec_len=32032,
name_len=44
Aborting journal on device dm-1.
ext3_abort called.

And a little bit later:
Assertion failure in dx_probe() at fs/ext3/namei.c:383: "dx_get_limit(entries)
== dx_root_limit(dir, root->info.info_length)"
