Suspend to ram has been broken on my Thinkpad x230 since v4.7-rc1.
Finally found the time and bisected it to this:

22e2f9fa63b0 iommu/vt-d: Use per-cpu IOVA caching

And after some googling found a fix and verified that it fixes the issue
for me:

iommu/vt-d: fix overflow of iommu->domains array
https://patchwork.kernel.org/patch/9158085/

The patch is not in Linus' tree yet, hopefully will be soon.

Thorsten, your regression list is _very_ useful and saves a lot of time.
I hope you have the time and energy to continue maintaining it.
