Resume from suspend fails when kvm/kvm_intel loaded on Lenovo X60
Last modified: 2013-01-10 04:52:58 EST
With the kvm/kvm_intel modules loaded, my laptop will suspend to ram, but will
never resume. There will be some hard disk activity, but the little moon sleep
light will stay on. caps lock keys etc do not work either. Unloading the kvm
modules allows suspend and resume to work properly.
$> lshal | grep system.hardware.version
system.hardware.product = '1709G3U' (string)
Intel(R) Core(TM)2 CPU T7200 @2.00GHz
Does this still happen with the latest rawhide kernel? Thanks.
Sadly, I can't tell. Something else is breaking suspend/resume with kernel
2.6.21-1.3194. I'll update this bug when I can determine if KVM is a problem or not.

As I mentioned in 242333, I see the same thing on a Dell XPS M1210.
Having the following in /etc/pm/config.d/unload_modules fixes the problem,
allowing the machine to resume:
SUSPEND_MODULES="iwl3945 mac80211 kvm_intel kvm"
removing kvm_intel and kvm from that list renders the system unable to resume.
I wonder if the kvm patches mentioned here for the kernel are any help:

I've added this to the suspend site, thanks.
To make for a smoother user experience, can we do one of these please (by order
- make the kvm kernel modules handle suspend
- make the kvm kernel modules self-unload on sleep
- drop a file in /etc/pm/sleep.d/ to make sure kvm-amd, kvm-intel and kvm are
on the SUSPEND_MODULES list
2.6.23-rc1 now has reliable suspend-to-ram. It should be easy to backport the
patches to earlier kernels.

Agreed, you guys rock. DaveJ, can we add this to the F7 kernel when you next do
As far as i can tell, this bug is fixed in F-7 and F-8, and could be closed.

Agreed. I'll close it.
