I have experienced this error too, I'm using Linux 3.13.4. I've attached a picture of the stacktrace. 

The error does not occur anymore if i disable these options:

--- IOMMU Hardware Support
[ ]  Support for Intel IOMMU using DMA Remapping Devices
[ ]  Enable Intel DMA Remapping Devices by default
[ ]  Support for Interrupt Remapping

Hardware: 
Gigabyte Z87X-D3H 
Intel Xeon E3-1240v3
16 GB RAM
GeForce GTX 560 Ti
GeForce GT 610

Picture of a stacktrace, Kernel 3.13.4

I have the same problem on an IBM IntelliStation Z Pro Type 9228

Kernel Stack Trace

I can trace your bug to these lines.
	if (unlikely(cpu_is_offline(cpu))) {
		WARN_ON(1);
		return;
	}
Seems that due to your CPU being offline at this point , it goes
into the WARN_ON which warns but doesn't reschedule. There are 
two issues here.
1. Your CPU core is offline and therefore needs to be online before this
function
2.WARN_ON is there but we need to reschedule to another core or we panic
as it seems in your trace attachment.

I'm experiencing exactly the same problem with kernels 3.18.4 and 3.19-rc6. Everything worked fine with kernels 3.14 through 3.17. 

I tried to change some kernel options (including disabling all "IOMMU Hardware Support" options as suggested above) to no avail.

Coming back to this after some some time now, I can report that I still get the same crash with mainline kernel 4.1 but only when my extern USB 3.0 HD is attached. I didn't see it happening anymore without it beign attached but now it consistently crashes whenever I forgot to detach my hard drive during boot.
