dmesg
System Environment:
--------------------------
Platform: Ivybridge
Kernel: (drm-intel-fixes) cd66407810869709e0d6764409137d48c6812cfc
Bug detailed description:
-----------------------------
Start system with next-queued or next-fixed debug_build kernel, then run
module_reload, you will see "[ INFO: possible circular locking dependency
detected ]" in dmesg. It happens on next-queued and next-fixed branch.
I try to bisect, but find it also exists in kernel 3.9.0-rc6.
Reproduce steps:
---------------------------
1. start system with debug kernel
2 ./module_reload
2. see dmesg</pre>
