Hmm, 2.6.33 -stable has commit 846f99749ab68bbc7f75c74fec305de675b1a1bf?
Actually, these 3 commits fixed it:
6992f5334995af474c2b58d010d08bc597f0f2fe sysfs: Use one lockdep class
per sysfs ttribute.
a2db6842873c8e5a70652f278d469128cb52db70 sysfs: Only take active
references on attributes.
e72ceb8ccac5f770b3e696e09bb673dca7024b20 sysfs: Remove sysfs_get/put_active_two
However, there are many other patches needed to amend these, so I think
it's not suitable for -stable to include, perhaps a revert of
846f99749ab68bbc7f75c74fec305de675b1a1bf is better.
Adding Greg into Cc.
Thanks.
