Thanks for the report; sorry it fell through the cracks.
Is this problem reproducible? If so, can you try to reproduce it on
v3.11? Can you please attach a complete dmesg log and "lspci -vv" (as
root) output to the bugzilla?
The BUG_ON you're hitting is here, but I don't know what it means:
#ifdef CONFIG_GENERIC_HARDIRQS
for (i = 0; i < nvec; i++)
BUG_ON(irq_has_action(entry->irq + i));
#endif

What's the status of this? Is it still a problem? Should we just
close the bug as unreproducible?

Thanks.
Note that this appears to be vanilla v3.12, which has e1000e version
2.3.2-k in it. Intel maintains newer drivers out-of-tree at
http://sourceforge.net/projects/e1000/, and it's possible this is some
bug that has already been fixed. The current version there looks like
e1000e-2.5.4, released 2013-09-05.
I think only the Intel folks can help you out with this.
