Ok, I meant those:

http://marc.info/?l=linux-kernel&m=135984592927219

They fix the link detection issue on my x230. So let's see. The first one is:

* https://patchwork.kernel.org/patch/2001211/ (e1000e: fix pci device enable
counter balance)

Rafael said this one is a real bugfix. Looks like e1000e maintainers are
picking that one?

* pci-pm-fix-e1000e-runtime-suspend.patch

I don't see that one in your tree.

* pci-pm-clear-state_saved-during-suspend.patch

I can see this one in your tree: http://git.kernel.org/?p=linux/kernel/git/helgaas/pci.git;a=commitdiff;h=82fee4d67ab86d6fe5eb0f9a9e988ca9d654d765

With the imminence of the 3.8 release, we probably want to wait for
after the merge window and retest again, then apply and packport stuff,
if needed.

And the NMI issue is still unfixed so this needs more work, AFAICT. Oh
well, after the merge window.
