Dear all,
after updating to latest :
2.6.29-0.179.rc6.git5.fc11.i586, I see the following from dmesg
SELinux: Context unconfined_u:object_r:unconfined_cron_spool_t:s0 is not valid (left unmapped).
[drm:drm_mode_getfb] *ERROR* invalid framebuffer id

[ INFO: possible circular locking dependency detected ]
2.6.29-0.179.rc6.git5.fc11.i586 #1
-------------------------------------------------------
Xorg/2708 is trying to acquire lock:
(&mm->mmap_sem){----}, at: [<c049117b>] might_fault+0x48/0x85
but task is already holding lock:
(&dev->struct_mutex){--..}, at: [<f7ddc9ff>] i915_gem_execbuffer+0xd7/0xa1c [i915]
which lock already depends on the new lock.
the existing dependency chain (in reverse order) is:
-> #1 (&dev->struct_mutex){--..}:
[<c0450b4e>] __lock_acquire+0x970/0xace
[<c0450d07>] lock_acquire+0x5b/0x81

other info that might help us debug this:
1 lock held by Xorg/2708:
