Can you please build your kernel with KALLSYSMS_ALL enabled, so we get
a symbolic resolution of the call trace.
You can also try and enable CONFIG_PROVE_LOCKING. That will give us
even more detailed information about the problem at hand. Note, that
CONFIG_PROVE_LOCKING slows down your kernel, so don't try to run on a
production environment.
I found the reason: xfs mount with filestreams option.
