Hi,

I am following the "frequent lockups in 3.18rc4" thread (see [0]).

So, people still work on it, and one fixlet was going towards the sched/x86.
Is there an update of your patchset [1] (especially of patch 2/2 [2]) around?

One good thing in the discussion of [0] would be a short summarize and
config-parameters to test with.

Thanks in advance.

Regards,

P.S.: I have applied the 3 patches of Linux on top of Linux v3.18.1
and testing with that.

Linus Torvalds (3):
      x86: mm: move mmap_sem unlock from mm_fault_error() to caller
      x86: mm: consolidate VM_FAULT_RETRY handling
      x86: mm: fix VM_FAULT_RETRY handling
