Subject: 3.6.11 SLAB: Unable to allocate memory on node 0 (gfp=0xd0)

Hello,

Below is a dmesg of a SLAB issue I did not yet see before.
A 3.6.11 kernel on a x86_64 Fedora 17 box from kernel.org.
I attached a SATA disk and mounted the encrypted FS after using luksOpen.

So what went wrong?
I do have another instance of this failure below.
