I am on tip.git at cfbf8d4 Linux 3.14-rc4. and I don't see the problem (using Ubuntu Saucy). Also IVB, model 58? Yes.

Given what you commented out, it seems like you're saying something goes wrong with pcigetdevice(). Probably. I'll add some debug printk's tomorrow to shed some more light on the matter.

Am I missing some pm callbacks? Dunno. What do you mean by "pm callbacks" exactly? I don't know that code so I have to ask. power management callbacks.

The uncore IMC is not used internally. By IMC I'm assuming this PIC dev: #define PCIDEVICEIDINTELIVBIMC 0x0154 ? Yes. Needs to point to the DRAM controller.

And "internally" means by BIOS or something behind the curtains like SMM...? I meant by the kernel.
