Steven Rostedt reported problems versus the signal handling code and Koehrer Mathias reported the same. The patch in question has been reverted and a patch currently sitting in -mm has been added which provides the same functionality (running the constructor with enabled interrupts). Patch provided by Thomas Gleixner. The stable trees which carry the delay-ctor patches should be updated to this. Reverting the patch at least prevents the BUG. Latencywise the slub patch mm-slub-move-slab-initialization-into-irq-enabled-re.patch is the one which wants to be ported back.
