Hi,

my machine does not wake from suspend to RAM on my box running the -next
kernel. The last thing I see is "Disabling non-boot CPUs ...". I
bisected it to this commit:

commit 7ec98e15aa049b7a2ca73485f31cf4f90c34e2dd
Author: Thomas Gleixner <tglx@xxxxxxxxxxxxx>
Date:   Thu Feb 21 22:51:39 2013 +0000

     timekeeping: Delay update of clock->cycle_last


Reverting that one on the top of -next-20130419 makes it work again.


I also tried it inside a VM using suspend to disk. There, it behaves
like it takes a minute or so to wake up. So I tried to wait on the real
HW too, but it never resumes there.

Thanks for chasing this down! Sorry for the trouble, does the following fix resolve this?

Nevermind, I see Thomas already provided the same fix yesterday.

thanks
