Sorry - that's all that I got on the console.

>> ip is at new_slab+0x90/0x680

The instruction there is a "fetchadd8.rel r14=[r9],1", so we are doing an atomic add.

r9 was computed as 32 + return value from a call to allocate_slab()

So I think we are inside the inlined "inc_slabs_node()" call on line 1357 of mm/slub.c
