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. regards, -- js suse labs
