Subject: kernel panic 3.11.7 in kmem_cache_alloc+0x66/0x150

Hi,

Last weekend one of our machines showed some interesting behaviour, where
processes seemed to be crashing randomly. Further inspection showed that
all the oopses in syslog were on core #12, and had
kmem_cache_alloc+0x66/0x150 as the RIP, except for the second one, which had
kmem_cache_alloc_trace+0x6a/0x140 .

The first oops was:

This machine contains two hexacore xeons running with HT enabled, so 24
cores in total, and has 128 GB of RAM, and all NUMA stuff has been disabled
in the bios (so this machine behaves as one big machine). It's running a
vanilla 3.11.7 , can provide you with the config if needed.

This looks to me like it's the same as the problem described in
https://lkml.org/lkml/headers/2013/11/30/153 , are there any things to try
besides upgrading to a 3.13 ?
(This is the second machine on which we have seen this..)

Regards,
Jasper
