INFO: possible circular locking dependency detected



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

       [<c0403f92>] syscall_call+0x7/0xb
       [<ffffffff>] 0xffffffff

       [<f7ddcb48>] i915_gem_execbuffer+0x220/0xa1c [i915]
       [<f7d8578f>] drm_ioctl+0x1b7/0x236 [drm]
       [<c04b4628>] vfs_ioctl+0x5a/0x74

       [<c0403f92>] syscall_call+0x7/0xb
       [<ffffffff>] 0xffffffff

other info that might help us debug this:

1 lock held by Xorg/2708:

Other than that the machine is working:

Send this information to the Smolt server? (y/n) y
but I got the following:

Server Message: "Critical [20]: Invalid Token"
Traceback (most recent call last):
  File "/usr/bin/smoltSendProfile", line 176, in <module>
    timeout=opts.timeout)

    raise ServerError, _('Could not contact server: %s') % line.split('ServerMessage: ')[1]
