[ INFO: possible circular locking dependency detected ]
2.6.22-rc6-mm1 #4
-------------------------------------------------------
evolution-data-/469063 is trying to acquire lock:
 (&mm->mmap_sem){----}, at: [<ffffffff80530d4c>] do_page_fault+0x17c/0x8c0

but task is already holding lock:
 (&data->latch){----}, at: [<ffffffff8034ebb1>] get_exclusive_access+0x11/0x20

which lock already depends on the new lock.
