With Jan Kara'a debugging patch on top of 2.6.32 final I get the following
after shutdown -r:
Unmounting file systems: sb orphan head is 22
sb_info orphan list:
inode sda2:22 at cc7c1618: mode 100600, nlink 0, next 13, i_count=2501
dentry=
NULL
iget IPs:
c009e590,
c009dd08,
inode sda2:13 at d1d932b8: mode 100600, nlink 0, next 12, i_count=2 dentry=
NULL
iget IPs:
c009e590,
c009dd08,
inode sda2:12 at d1de0618: mode 100600, nlink 0, next 0, i_count=1 dentry=
NULL
iget IPs:

c009dd08,
kernel BUG at fs/ext3/super.c:450!
c009e590 is fs/fs-writeback.c:writeback_inodes_wb(), line 681.
c009dd08 is fs/fs-writeback.c:wait_sb_inodes(), line 1170.
I get this with both gcc-4.3.4 and gcc-4.4.2 compiled kernels.
On a second machine I got a similar result, except the three inodes had only
one iget IP recorded, and it was the one in writeback_inodes_wb().
