next-20160607 and 4.7.0-rc2-00004-g3613a62 (Linus' tree
of the moment) so far today... Linus' tree is still OK (because
it has 7f9bef9) and linux-next is still busted (for me).

I'll keep on bisecting using the suggestions that Paolo sent...

I see.

I think I'll need to drop the latest ACPICA changes from linux-next then.

Let me try to do that and please test linux-next again tomorrow.

Thanks,

Linux-next fails to boot properly for me, but Linux 4.7-rc2 from
Linus' tree boots fine.

I got started bisecting next-20160603 last Friday, but didn't get done.

git bisect start '64289ca' '7f9bef9'

I picked 7f9bef9 as the good commit to start with because I knew
I needed 7f9bef9 or else my QEMU-KVM would crash. Before I started
the bisection, I verified that 7f9bef9 was indeed good by checking
out a branch from next-20160603 with 7f9bef9 as the HEAD and
building it: git checkout -b gas 7f9bef9

Today I got next-20160606 and checked to see if the same failure
occurred - it did. So I continued with the bisection of next-20160603.

I arrived at 407aa3ff6f54ea2be7959639d664ae5183e2e9f8 as the bad commit.


407aa3f is a rather complex commit... there is a problem with it,
but I'm not sure what to do next... both 7f9bef9 and 407aa3f are
related to ACPICA...

It looks like this commit

https://git.kernel.org/cgit/linux/kernel/git/rafael/linux-pm.git/commit/?h=acpica-fixes&id=7f9bef9debafcb767d00efb177d0f2edd4940eab

should fix the problem for you.

Thanks,
Rafael
