Yesterday, I synced with Linus' tree, but couldn't boot. Crashed with
this call trace:

  https://gist.githubusercontent.com/ammarfaizi2/3ba41f13517be4bae70cde869347d259/raw/0ac09b3e1d90d51c3fed14ca9f837f45d7730f0a/crash.jpg

This morning, I synced with Linus' tree again, still the same result.

I suspect it's related to pci. I'm still bisecting. I've successfully
narrowed it down to this pci pull.

Now, I am testing:

I'll be back to it later. git bisect says:

  Bisecting: 65 revisions left to test after this (roughly 6 steps)
