Subjectrecent 2.6.26 kernel hangs at suspend
I can simulate this and it's definitely a bug, but I could only bisect
up to a point and the kernel would not boot after tat.

The bug is that my X60s notebook would not suspend-to-ram on the 2nd try.

Boot up -> suspend to ram -> ok -> resume -> suspend to ram -> hang!

The hang would only happen while in X.

If I don't enter X, it'll not hang on suspend to ram.

I tried git bisect but can only get to this commit
4a27214d7be31e122db4102166f49ec15958e8e9.

The next commit b82287587ef9917afbea5fcbf7aa63424b6f3719 would not boot.

How can I get pass the "bad" commit. I've tried "skip" or "next", but
still won't boot.

And it doesn't seem like it's X as 2.6.25 kernel can suspend and
resume many times in X without problem.

Here's how I bisected ...
